The Microsoft Face API uses state-of-the-art cloud-based face algorithms to detect and recognize human faces in images. Capabilities include features like face detection, face verification, and face grouping to organize faces into groups based on their visual similarity.

For operations that enable training at million-scale available beginning March 1,a transaction is counted for every 1, images trained.

Each operation in this category is rounded up to the nearest increment of 1, images. Please refer to the documentation for the complete list and detailed descriptions of operations.

Face Storage allows a subscription to store additional persisted faces when using person objects and face lists for identification, or for similarity matching with the Face API. For example, if your account used 10, persisted faces each day for the first half of the month and none the second half, you would be billed only for the 10, faces for the days stored. As a second example, if each day during the month you persist 1, faces for a few hours and then delete them each night, you would still be billed for 1, persisted faces each day.

The quota for the number of stored person groups is now 1 million, with up to 1 million persons per person group or face lists.

Offers a wide variety of image recognition solutions through their API. Their API endpoints include identifying gender, age, emotional depth, facial recognition in both photo and video, and more. The Animetrics Face Recognition API can be used to find human faces, detect feature points, correct for off-angle photographs, and ultimately perform facial recognition.

Information on facial features, including ears, nose, eyebrows, lips, chin are returned as coordinates on the image. The Animetrics Face Recognition API will also detect and return the gender and orientation, or "pose" of faces along 3 axes.

A special capability called "SetPose" is also available which allows the face to be re-rendered at a desired pose that is different than the captured pose. This is typically used when the facial photo is captured off-angle and a zero-corrected fully frontal image 0 degrees pitch, yaw, and roll is required.

Example: Identify faces in images

Detected facial features may be corrected or modified to improve the final results of subsequent steps. For example, an eye in the picture may be hidden or obscured; requesting just eye feature points, manually correcting their locations, and feeding this data into a more detailed request will help improve the accuracy of the additional feature point and pose detection.

Face Detection API that detects the location of human faces in your images. Learn more here. Use the Age and Gender endpoint to get data on predicted binary genders for each face and an age range of possible ages for the faces detected.

Detect and compare human faces. Identify previously tagged people in images. Recognize age, gender, and emotion in the photo. Provides coordinates for all faces detected and associated facial features such as eyes, nose, mouth, skin tone, and hair color. This API also returns several biometric features still in development to include gender, race, and age estimation. The offline SDK does not provide face recognition, but it can perform face detection, comparing, tracking and landmarks, all while the phone does not have cell service.

This API provides a suite of tools around facial detection and recognition within images. Capabilities provided include comparing two faces face recognitiondetecting the presence of faces within an image, and returning X,Y coordinates of faces detected in images. This API leverages machine learning and specifically deep convolutional neural networks built in TensorFlow. The Computer Vision API provides state-of-the-art algorithms to process images and return information.

Detect, analyze, recognize and compare faces, create your own face databases or use provided public ones. Generate average faces. With over 3, optimized computer vision algorithms, there are a lot of options for how developers can make use of this open-source computer vision and machine learning library.

Will you be using any of these APIs in your projects? The ability to process human face information is important in many different software scenarios. Example scenarios are security, natural user interface, image content analysis and management, mobile apps, and robotics.

The Face API provides several different functions. Each function is outlined in the following sections.

We shall be using the Microsoft. Face and Microsoft. Vision Nuget packages in our API app. I have also combined the code for uploading an image to Azure Blob storage in this new API app — ImageUtilitiesso that one can use all these functions together in an app if needed. In PowerApps, when a maker shares an app created using a custom connector, the connector is automatically shared and hence other users can use the app without needing to type in an API key.

This auto generates the definitions for all the reference classes like AnalysisResult and others used by the APIs in the swagger document. Since I have used the Swashbuckle feature to include XML Comments from my assembly to generate Summary and Description tags in swagger, it becomes quite handy for both the API registration and also for providing intelli-sense when authoring the functions from the PowerApps app.

I have used Visual Studio for the code used in this app. Extract the contents of the zip file and open the ImageUtilities. The list of APIs for reference is given below:. Open the Web. Config file with corresponding values from your Azure services.

Also populate the root end points for both the services as well. Once satisfied, publish the app to Azure. Refer to this article for a good tutorial for Publishing to Azure with Visual Studio. Download the swagger document. This is required to secure the PowerApps custom connector with AAD so that other users within the organization can use their own AAD credentials to authenticate against the connector for the app. The second AAD application is used to secure the custom connector registration and acquire delegated access to the ImageUtilitiesAPI app protected by the first application.

Browse to the PowerApps portaland add a custom connector as described in this article: Register and use custom connectors. Note down the Environment name where you are creating the Custom connector. If you are curious how, we have already added a security definitions in the SwaggerConfig file itself, using the c. OAuth2 "oauth2" method. You should be able to see all the actions and References imported from the swagger file in the Definition section as per screenshot below.

Every call to the Face API requires a subscription key. This key can be either passed through a query string parameter or specified in the request header. To pass the subscription key through a query string, see the request URL for the Face - Detect as an example:.

When you use a client library, the subscription key is passed in through the constructor of the FaceClient class. For example:. To get the subscription key, go to the Azure Marketplace from the Azure portal. For more information, see Subscriptions. Each person has several faces registered. The faces must be detected from the images. After all of these steps, you have a PersonGroup like the following image:. A person is a basic unit of identify.

A person can have one or more known faces registered. A PersonGroup is a collection of people. Each person is defined within a particular PersonGroup. Identification is done against a PersonGroup. The task is to create a PersonGroup, and then create the people in it, such as Anna, Bill, and Clare. The group ID that's specified to create the group is unique for each subscription.

The client library method is CreatePersonAsync. You can add a face to each person after they're created. When you use the client library, face detection is done through one of the Detect. Async methods of the FaceClient class. The following code demonstrates the process of how to detect a face from an image and add it to a person:. If the image contains more than one face, only the largest face is added.

You can add other faces to the person. You also can use the targetFace optional parameter for the AddPersonFaceAsync method to add other faces. Each face added to the person is given a unique persisted face ID. The PersonGroup must be trained before an identification can be performed by using it.

The PersonGroup must be retrained after you add or remove any person or if you edit a person's registered face. When you use the client library, it's a call to the TrainPersonGroupAsync method:. Training is an asynchronous process. It might not be finished even after the TrainPersonGroupAsync method returns. You might need to query the training status.

The following code demonstrates a simple logic of waiting for PersonGroup training to finish:. When the Face service performs identifications, it computes the similarity of a test face among all the faces within a group. It returns the most comparable persons for the testing face. The testing face must be detected by using the previous steps. Multiple face IDs can be identified at once. The result contains all the identified results.
