The FaceSDK library has the following technical specifications:
Face Detection
- Robust frontal face detection
- Detection of multiple faces in a photo
- Head rotation support: –30..30 degrees of in-plane rotation and –30..30 degrees out-of-plane rotation
- Determines in-plane face rotation angle
- Detection speed: as fast as 241 frames per second*, depending on resolution
- Realtime detection: 0.0041 sec (241 FPS)*, webcam resolution, –15..15 degrees of in-plane head rotation
- Reliable detection: 0.267 sec, digicam resolution, –30..30 degrees of in-plane head rotation
- Returned information for each detected face: (x,y) coordinates of face center, face width and rotation angle
- Easy configuration of face detection parameters
Face Matching
- Matching of two faces at given FAR (False Acceptance Rate) and FRR (False Rejection Rate)
- Enrollment time: 0.02 seconds (50 FPS)* (at webcam resoluton)
- Template Size: 16 kb
- Matching speed: 49700 faces per second*
- Returned information: facial similarity level
Facial Feature Detection
- Detection of 66 facial feature points (eyes, eyebrows, mouth, nose, face contour)
- Detection time: 0.104 seconds* (not including face detection stage)
- Allowed head rotation: –30..30 degrees of in-plane rotation, –10..10 degrees out-of-plane rotation
- Returned information: array of 66 (x,y) coordinates of each facial feature point
Eye Centers Detection
- Detection of eye centers only, detection time: 0.0064 seconds* (not including face detection stage)
- Returned information: two (x,y) coordinates of left eye center and right eye center
Multi-Core Support
- The library uses all available processor cores when executing face detection or recognition functions, to maximize performance.
Library Size
- The size of the redistributables does not exceed 21MB for each platform.
* Measured on Intel Core i7 930 processor with 8 threads
