Face Identification and Tracking in Live Video Streams
The revolutionary motion-based face recognition technology enables video-based identification of human subjects with no prior enrolment. The API automatically recognizes all faces encountered in a video stream, registering their complete biometric information captured from the many different views and angles, complete with live emotions and expressions. Each subject can be tracked seamlessly and automatically without specific enrolment. Enrolling a person is as simple as putting a name tag in a video. This can be done at any time, and the system will automatically identify that subject in all past, present and future videos. Enrolment-free identification is perfect for building CRM systems for registration desks, access and attendance control systems, surveillance and security applications.
How does it differ from existing systems? Most current video identification systems are based on key frame processing. In other words, they discard information available in the motion stream, and revert to still image recognition instead. This design approach requires a set of sophisticated preliminary enrolment procedures where the subject’s face is captured against plain background at various angles and posed expressions.
FaceSDK 6.1 implements a true motion-based video identification system. It automatically recognizes and tags all faces encountered in a video stream. Personalizing any identified subject becomes a simple matter of putting a name tag on it, or linking its tag to a database record. No special enrolment procedure is ever required. In addition, recognition rate is significantly higher in true motion-based recognition systems compared to traditional key frame-based ones. On comprehensive Multi-PIE tests, the recognition rate increases from 23% to 89% with video-based identification compared to key frame-based identification, considering that just a single image of a subject is enrolled and false acceptance rate is 0.06%.
The library can compare different faces, returning the degree of likeness. This allows identifying human faces appearing in still images or video streams by looking up face databases. Recognizing and identifying still images enables locating similar faces in driver’s license databases while helping detect duplicates. The system implements image indexing, creating compact templates for faster searching. This in turn allows building a range of security applications such as video surveillance and real-time access control systems. Many more features and higher performance are achievable in video-based surveillance systems using the new set of motion-based recognition algorithms.
FaceSDK is designed to perform equally well under varying lighting conditions. It works fine under daylight, fluorescent and incandescent lighting. When testing on a FRGC database, the library successfully identifies individuals in 93.9% of cases if acceptable false positive is 0.1%.
Face Detection in Stills and Videos
Luxand FaceSDK returns coordinates of all human faces appearing in the picture – or notifies if no face is found. FaceSDK can track all faces appearing in a video stream. It allows finding out if a new face appears in the frame, or if one of the subjects leaves the frame. This in turn enables easy implementation of people counting. When testing on the FERET dup1+gallery database (frontal passport-like photos) successfully detects 99.5% of faces, with only 0.05% false positives.
Eye Detection in Stills and Videos
FaceSDK detects coordinates of both eyes. Its high performance allows using this function on still images as well as in video streams in real-time. The ability to track eye movements enables building a variety of entertainment applications such as trying eyeglasses. An average error on FERET dup1+gallery is 3.1% of inter-ocular distance, while in 95% occurrences the error is less than 5.7% of inter-ocular distance. What do these numbers mean? They mean that, on average, if there are 100 pixels between the eyes, the eyes will be detected with the precision of +/- 3 pixels; and even if the error is greater than that, in 95% it’ll be less than 5 pixels.
Facial Feature Detection and Tracking
Luxand FaceSDK employs sophisticated algorithms to detect and track facial features quickly and reliably. The SDK returns the coordinates of 66 facial feature points including eyes, eye contours, eyebrows, lip contours, nose tip, and so on. The detection works in real-time on desktop and mobile, which allows performing smooth real-time tracking and transformations of facial features in live video. On desktop platforms, FaceSDK delivers true 60-fps performance on video streams, while video processing on mobile platforms such as Apple iPhone 6 is performed at 15 fps (higher rates are achievable on devices with more powerful platforms). The feature enables building applications adding new elements such as mustaches, eyeglasses or wigs; face morphing and augmented reality. By using FaceSDK, we built Mirror Reality: Aging, an application that ages faces in real time by detecting facial features in a video stream. Developers can implement mechanisms to analyze faces detecting emotions or rotation angle. Morph, animate, or transform human faces with the SDK!Continue reading »
An average error on a database of typical Web photos is 3.3% of inter-ocular distance, while in 95% occurrences the error is less than 8.1% of inter-ocular distance.
Automated Gender Recognition
FaceSDK can automatically identify subject’s gender based on a still image or motion stream. This feature is highly demanded by retail advertisers and marketing specialists. Identification quality is 93% on still pictures, and 97% in videos.
Facial Expression Recognition and Emotion Detection
FaceSDK helps detect human emotions by implementing facial expression recognition. The feature helps implement happiness meter and build applications that can detect blinking and sleeping. Facial expression recognition detects whether the person appearing in the picture or in a video stream has her eyes open (nearly 100% recognition rate on our internal tests) or whether the person is smiling (92% recognition rate).
FaceSDK supports all DirectX-compatible webcams that work in Windows. In addition, it supports all MJPEG IP-cameras on all supported platforms, including the popular AXIS range. This is just perfect for security, surveillance and access control applications, as the use of IP cameras allows getting information remotely from distant cameras. This also allows integrating FaceSDK into existing surveillance infrastructure.
FaceSDK includes a number of functions to load and manipulate images such as.bmp, .jpg, and .png, as well as memory buffers. The library can be used to resample images, rotate, crop, flip, and perform pixel-level editing. The files can be saved into the same format. These features are handy for building imaging applications even if you don’t immediately require any facial recognition features.
The library supports multi-core processors to boost the performance of face recognition, face detection, and facial feature detection. Today’s multi-core CPUs such as Intel i5, i7 and Xeon are used to their full potential. The library is completely thread-safe for using in multiple concurrent threads e.g. when receiving video streams from a large number of video cameras.
