Overall, Amazon Rekognition seems to perform much better than Google Cloud Vision. However, they are probably not in the scope of most end-user applications. Also, both services include a free usage tier for small monthly volumes. On the other hand, the set of labels detected by Amazon Rekognition seems to remain relevant, if not identical to the original results. Given the limited overlapping of the available features, we will focus on Object Detection, Face Detection, and Sentiment Detection. In contrast to the inefficiency of Vision in detecting misleading labels, Amazon Rekognition does a better job. According to most tech pundits, both the options involve features that are capable of giving users a run for their money. Object detection functionality is similar to both the services. Please refer to attached PDF for the partial specs. He's experienced in web development and software design, with a particular focus on frontend and UX. AWS has Amazon Rekognition, and Azure provides Microsoft Azure Cognitive Services as image and video recognition APIs. This means that once you have invoked the API with N requests, you have to wait until the N responses are generated and sent over the network. Neither Rekognition nor Vision supports the uploading of images from URLs that are arbitrary by nature. If you're simply trying to pull a line or two of text from a picture shot in the wild, like street signs or billboards, (ie: not a document or form) I'd recommend Amazon Rekognition. It also identifies an additional “Unknown” value for very rare cases that we did not encounter during this analysis. By collapsing such labels into one, the total number of detected labels is 111 and the relevance rate goes down to 87.3%. Also, we should note that for volumes above 20M, Google might be open to building custom solutions, while Rekognition’s pricing will get cheaper for volumes above 100M images. Both Google Cloud Vision and Amazon Rekognition provide two ways to feed the corresponding API: The first method is less efficient and more difficult to measure in terms of network performance since the body size of each request will be considerably large. Although both services offer free usage, it’s worth mentioning that the AWS Free Tier is only valid for the first 12 months for each account. The latter is a better choice compared to the former for image uploading as it performs the task without compromising the quality. There are numerous services available for image recognition, but we decided to test the two leading options: Amazon’s ‘Image Rekognition’ and Google’s ‘Vision API’. While Google’s service accepts images only from Google Cloud Storage, Amazon’s version of the service accepts images from Amazon S3. Alex is a Software Engineer with a great passion for music and web technologies. Tests have not revealed any performance or quality issues based on the image format, although lossy formats such as JPEG might show worse results at very low resolutions (i.e. Here is what Amazon claims: Text detection is a capability of Amazon Rekognition that allows you to detect and recognize text within an image or a video, such as street names, captions, product names, overlaid graphics, video subtitles, and vehicular license plates. However, we are looking for a complete solution for our use case which they did not provide. As well as for Object Detection, Amazon Rekognition has shown a very good rotational invariance.

Google Cloud Vision API enables you to understand the content of an image including categories, objects and faces, words, and more. Google vs Amazon. by URL) might help speed up API adoption, while improving the quality of their Face Detection features will inspire greater trust from users. Processing multiple images is a common use case, eventually even concurrently. It is best to fully flesh out your use cases before choosing which service to use. While Google Cloud Vision aggregates every API call in a single HTTP endpoint (images:annotate), Amazon Rekognition defines one HTTP endpoint for each functionality (DetectLabels, DetectFaces, etc.). Cloud Skills and Real Guidance for Your Organization: Our Special Campaign Begins! Amazon Rekognition uses advanced technology for face detection in images and video. Amazon Rekognition just provides one size fits all. Proven to build cloud skills. In order to use it, we had to send the entire file, or Technology majors such as Google and Amazon have stepped into the arena with an impressive line of services for detecting images, videos and objects. Instead, Google Cloud Vision failed in two cases by providing either no labels above 70% confidence or misleading labels with high confidence. Amazon Rekognition is better at detecting individual objects such as humans, glasses, etc. On the other hand, GCP offers media solutions through official partners that are based on Google’s global infrastructure such as Zencoder, Telestream, Bitmovin, etc. Quality will be evaluated more objectively with the support of data. The price factor and face detection at varied angles are the two aspects that give Rekognition an edge over Google Vision. A line is a string of equally spaced words. Google Cloud Vision’s biggest issue seems to be rotational invariance, although it might be transparently added to the deep learning model in the future. For example: The AWS Free Tier has been considered only for Scenario 1 since it would not impact the overall cost in the other cases ($5 difference). Based on the results illustrated above, let’s consider the main customer use cases and evaluate the more suitable solution, without considering pricing: We’d like to hear from you. This can be attributed to the advanced technology of Amazon relating to rotational in-variance. In addition to the obvious computational advantages, such information would also be useful for object tracking scenarios. Moreover, the charges of using both the services depend upon your request to process images. Google Cloud Vision and Amazon Rekognition offer a broad spectrum of solutions, some of which are comparable in terms of functional details, quality, performance, and costs. While Google Cloud Vision is more expensive, its pricing model is also easier to understand. One of the highlights of this sophisticated technology is that it does not necessitate users to have any special kind of training or knowledge such as machine learning to operate. While these options do not support animated images and videos, Google’s service only supports the first frame in the case of animated images. The following table summarizes the platforms’ performance for emotion detection. For example, a driver's license number is detected as a line. It is Amazon's answer to Google's Cloud Vision API, being a complex product for the segmentation and classification of visual content. Google Cloud Vision is more mature and comes with more flexible API conventions, multiple image formats, and native batch support. That is to say, the vendors bill you for the number of images that you process via their services. Cloud Academy Referrals: Get $20 for Every Friend Who Subscribes! Read on to find out the answer to these questions. This is because Object Detection is far more expensive than Face Detection at higher volumes. Don’t force platforms to replace communities with algorithms, Epic Isn’t suing Apple for the 30% cut, They’re Suing Them for Something Else, Inside Amazon’s Robotic Fulfillment Center, Why Ecosia Is The Must-Use Search Engine Right Now. Although both services can detect emotions, which are returned as additional landmarks by the face detection API, they were trained to extract different types of emotions, and in different formats. Vision’s responses will also contain a reference to Google’s Knowledge Graph, which can be useful for further processing of synonyms, related concepts, and so on. The limited emotional range provided by Google Cloud Vision doesn’t make the comparison completely fair. Being able to fetch external images (e.g. Amazon Rekognition seems to have detection issues with black and white images and elderly people, while Google Cloud Vision seems to have more problems with obstacles and background/foreground confusion. It classifies these emotions with four labels: “likely”, “unlikely”, “very likely”, and “very unlikely”. On the other hand, Vision’s free usage includes 1,000 units per month for each functionality, forever. The following table compares the results for each sub-category. Both services have a wide margin of improvement regarding batch/video support and more advanced features such as image search, object localization, and object tracking (video). Amazon Rekognition’s support is limited to JPG and PNG formats, while Google Cloud Vision currently supports most of the image formats used on the Web, including GIF, BMP, WebP, Raw, Ico, etc. Finally, the cost analysis will be modeled on real-world scenarios and based on the publicly available pricing. This limitation is even more important when considering the wide range of emotional shades often found within the same image. The emotional set chosen by Amazon is almost identical to these universal emotions, even if Amazon chose to include calmness and confusion instead of fear. Google worked much better but still required a few tweaks to get what I wanted. Amazon Rekognition is a much younger product and it landed on the AI market with very competitive pricing and features. This is partially due to the limited emotional range chosen by Google, but it also seems to be an intrinsic training issue. On the other hand, Vision is often incapable of detecting any emotion at all. In line with this trend, companies have started investing in reliable services for the segmentation and classification of visual content. The situation is slightly different for Face Detection at very high volumes, where the pricing difference is roughly constant. Google Cloud Vision vs Amazon Rekognition: Detection of Face & Objects In contrast to the inefficiency of Vision in detecting misleading labels, Amazon Rekognition does a better job. The 12 AWS Certifications: Which is Right for You and Your Team? The API always returns a list of labels that are sorted by the corresponding confidence score. We could have utilized Google Cloud Vision/Google Document AI and Amazon Textract/Amazon Rekognition Text Detection to further perform OCR on bounding boxes through their APIs once we have found the bounding boxes information from the custom label models. Google Cloud Vision API - Understand the content of an image by encapsulating powerful machine learning models. Obviously, each service is trained on a different set of labels, and it’s difficult to directly compare the results for a given image. Testing Conditions For this article, we will be focusing on its components for face recognition and analysis. Within AWS, API consumers may use Amazon Elastic Transcoder to process video files and extract images and thumbnails into S3 for further processing. That’s why we made our quality and performance analysis on a small, custom dataset of 20 images, organized into four size categories: Each category contains five images with a random distribution of people, objects, indoor, outdoor, panoramas, cities, etc. Objective-driven. If no specific emotion is detected, the “Very Unlikely” label will be used. Work required: 1. One additional note related to rotational invariance: Non-exhaustive tests have shown that Google Cloud Vision tends to perform worse when the images are rotated (up to 90°). The emotional confidence is given in the form of a numerical value between 0 and 100. Micro-Blog 1 of 3: What I Wish I Knew Before I Took the CKAD: Multi-What? Vision is considered exceptionally good for face detection, but lacks at face search and comparison. compared to Google Cloud Vision. Despite a lower relevance rate, Amazon Rekognition always managed to detect at least one relevant label for each image. Native video support would definitely make things easier, and it would open the door to new video-related functionalities such as object tracking, video search, etc. Despite its efficiency, the Inlined Image enables interesting scenarios such as web-based interfaces or browser extensions where Cloud Storage capabilities might be unavailable or even wasteful. Google Cloud Vision API has a broader approval, being mentioned in 24 company … Note: All of the cost projections described below do not include storage costs. Its Object Detection functionality generates much more relevant labels, and its Face Detection currently seems more mature as well, although it’s not quite perfect yet. Both services do not require any upfront charges, and you pay based on the number of images processed per month. Comparing Face Recognition: Kairos vs Amazon vs Microsoft vs Google vs FacePlusPlus vs SenseTime At the top of 2017, we brought you a pretty comprehensive comparison article that positioned Face Recognition companies, including us, side by side for a look at how we all stacked up. Still, the the decision to make a choice remains with individual. Google Vision API has an upper hand in this respect in the sense that it supports a wide range of formats such as ICO, Raw, WebP, BMP, GIF, PNG, and JPG. Published July 18, 2019. link Introduction. Videos and animated images are not supported, although Google Cloud Vision will accept animated GIFs and consider only the first frame. The first three charts show the pricing differentiation for Object Detection, although the first two charts also hold for Face Detection. Finally, the same pricing can be projected into real scenarios and the corresponding budget. Also, the API is always synchronous. Please refer to attached PDF for the partial specs. The emotional confidence is given in the form of a categorical estimate with labels such as “Very Unlikely,” “Unlikely,” “Possible,” “Likely,” and “Very Likely.” Such estimates are returned for each detected face and for each possible emotion. Vision’s batch processing support is limited to 8MB per request. Amazon Rekognition makes it easy to add image and video analysis to your applications using proven, highly scalable, deep learning technology that requires no machine learning expertise to use. On the other hand, the Cloud Storage alternative allows API consumers to avoid network inefficiency and reuse uploaded files. Both APIs accept and return JSON data that is passed as the body of HTTP POST requests. The Object Detection functionality of Google Cloud Vision and Amazon Rekognition is almost identical, both syntactically and semantically. Amazon Rekognition’s support is limited to JPG and PNG formats, while Google Cloud Vision currently supports most of the image formats used on the Web, including GIF, BMP, WebP, Raw, Ico, etc. Google has come up with Google Cloud Vision API which, according to the company, does a decent job at detecting unusual images from the usual ones. Amazon Rekognition is Amazon’s advanced technology for face and video detection which has been developed by its computer vision scientists. Skill Validation. In contrast, the service by Google is trained to detect only four types of emotions: surprise, anger, sorrow, and joy. Ringing in a new era of police surveillance? While the first two scenarios are intrinsically difficult because of missing information, the third case might improve over time with a more specialized pattern recognition layer. If we think of a video as a sequence of frames, API consumers would need to choose a suitable frame rate and manually extract images before uploading them to the Cloud Storage service. Thus, one can conclude that these services accept only vendor-based images. Many have conducted detailed analysis of Google Vision API and Amazon’s version of API that also suggest that the former is less reliable in detecting images when they are rotated at 90 degrees. AWS Certification Practice Exam: What to Expect from Test Questions, Cloud Academy Nominated High Performer in G2 Summer 2020 Reports, AWS Certified Solutions Architect Associate: A Study Guide. Despite the lower number of labels, 93.6% of Vision’s labels turned out to be relevant (8 errors). The following table recaps the main high-level features and corresponding support on both platforms. Learn how to create a sample custom Box Skill by using Amazon Rekognition Image and AWS Lambda to apply computer vision to image files in Box. Deciding whether a face is happy or surprised, angry or confused, sad or calm can be a tough job even for humans. As far as uploading images on both the services is concerned, users have the choice to upload either inline images or from the cloud storage. During one of the Azure academy we held for Overnet Education, our partner for training, we dealt with the subject of image recognition, that generated interest among students. Note: Each services has its own pros and cons. Tesseract OCR - Tesseract Open Source OCR Engine However, they believe it is easier said than done for common users to make a choice at the outset without considering the features of both the options. Each scenario is meant to be self-contained and to represent a worst-case estimate of the monthly load. While both the services are based on distinct technologies, they provide almost similar outcomes in certain cases. Amazon Rekognition, latest addition from Amazon, is its answer to Google’s product for the detection of faces, objects, and images. As mentioned previously, Google’s price is always higher unless we consider volumes of up to 3,000 images without the AWS Free Tier. Amazon Rekognition is the company's effort to create software that can identify anything it's looking at -- most notably faces. By increasing the dataset size, relevance scores will converge to a more meaningful result, although even partial data show a consistent predominance of Google Cloud Vision. Comparing image tagging APIs: Google Vision, Microsoft Cognitive Services, Amazon Rekognition and Clarifai Other than that, Rekognition is relatively cheaper than Google Cloud Vision/Video. A sentiment detection API should be able to detect such shades and eventually provide the API consumer with multiple emotions and a relatively granular confidence. Overall, the analysis shows that Google’s solution is always more expensive, apart for low monthly volumes (below 3,000 images) and without considering the AWS Free Tier of 5,000 images. 2019 Examples to Compare OCR Services: Amazon Textract/Rekognition vs Google Vision vs Microsoft Cognitive Services. Amazon Web Services, The cloud skills platform of choice for teams & innovators. Blog / By Bill Harding. -, _, +, *, and #. For this test I tried both Google’s Vision and Amazon Rekognition.

On the other hand, Google Cloud offers Cloud vision API, AutoML Video Intelligence Classification API, Cloud Video Intelligence, and AutoML Vision API. The two tech giants are approaching the powerful technology in different ways. Overall, Vision detected 125 labels (6.25 per image, on average), while Rekognition detected 129 labels (6.45 per image, on average). Such a solution would be fully integrated into the AWS console, as Elastic Transcoder is part of the AWS suite. Google Cloud Vision: 1923 (2.5% error) Amazon Rekognition: 1874 (5.0% error) Microsoft Cognitive Services: 1924 (2.4% error) Sightengine: 1942 (1.5% error) When starting your training job, you have the ability to choose between large or compact models based on your downstream inference time needs in Azure and Google Cloud. Preferably at a low price. For now, only Google Cloud Vision supports batch processing. We will focus on the types of data that can be used as input and the supported ways for providing APIs with input data. Both services only accept raster image files (i.e. below 1MP). Google Cloud Vision pricing model (up to 20M images), Amazon Rekognition pricing model (up to 120M images). Gives you free cost for the first 1,000 minutes of video and 5,000 images per month for the first year. Though one can add such images to these services via a third data source that needs additional networking which can be expensive. Image recognition technology is quite precise and is improving each day. Certification Learning Paths. This post is a fact-based comparative analysis on Google Vision vs. Amazon Rekognition and will focus on the technical aspects that differentiate the two services. For this test I tried both Google’s Vision and Amazon Rekognition. In addition, Amazon isn’t too far behind in this regard. Only 89% of Rekognition’s labels were relevant (14 errors). It’s worth noting that Scenarios 3-4 and 5-6 cost the same within Amazon Rekognition (as they involve the same number of API calls), while the cost is substantially different for Google Cloud Vision. Additional SVG support would be useful in some scenarios, but for now, the rasterization process is delegated to the API consumer. You do not need to pay in advance to use these services. Both services have one thing in common. Since Vision’s API supports multiple annotations per API call, the pricing is based on billable units (e.g. Business organizations and, … Amazon’s service for face recognition fares well with images that are loaded either in PNG or JPG formats.
