Top 10 Facial Recognition APIs & Software of 2021

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.

Kairos is a leading face recognition AI company with an ethical approach to identity, that reflects our globally diverse communities. Through computer vision and deep learning, we recognize faces in videos, photos, and the real-world—our innovative API platform simplifies how developers and businesses integrate human identity into their software. We help our customers combat identity fraud, meet regulatory compliance, and enable more profitable customer experiences.

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. I.e. as if the photo was taken with respect to any desired angle relative to the camera. 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.

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.

With over 1,000 calls per month in the free pricing tier and only $0.0024 per extra API call, this API is a really affordable option for developers wanting to use a facial recognition API.

Face Detection API that detects the location of human faces in your images. Use our Face Details API to detect faces, gender, age, and other facial features. Learn more here.

Easily integrate our Computer Vision API to add some Machine Learning magic✨ to your app. At inferdo, we pride ourselves in our ability to offer state-of-the-art, pre-trained deep learning models, but also our ability to efficiently serve them at scale. That means we can pass the savings on to you! Simply provide an image URL to our API and we'll handle the rest.

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.

Some highlights of this API include:

• Searching for people in a specific photo
• Verification
• Looking for a specific person in the collection of photos
• Detect the gender, age and emotions on photo
• Create the gallery to store images in a cloud with face recognition

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.

Overview of Features

The API accepts a URL to an image and returns the following information:

Coordinates (Box - Top Left XY; Bottom Right XY)

• Face
• Left Eye
• Right Eye
• Mouth
• Nose

Analytics

• Face to Image Ratio
• Hair Color
• Skin Color
• Eye Color

This API also has an offline SDK for iOS & Android for you to use. 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 has 2 endpoints:

• Face Detection - Detect the information of the given photo(e.g. face location, age, race, gender etc.)
• Face Landmark - Get 1000 key points of the face from the uploading image or the face mark face_token detected by the Detect API, and accurately locate the facial features and facial contours.

This API provides a suite of tools around facial detection and recognition within images. Capabilities provided include comparing two faces (face recognition), detecting 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.
