Your face tells everything
Extract emotional insights from facial emotions
Optical Flow based Tracking
Optical flow is defined as spatio-temporal image brightness variations. To track a face across a sequence of frames, we use Lucas-Kanade optical flow algorithm to estimate the motion of extracted facial features between adjacent frames in the sequence.
CAMShift based Tracking
The CAMShift algorithm is an adaption of the Mean Shift algorithm for object tracking. The Mean Shift algorithm is a robust, non-parametric technique that climbs the gradient of a probability distribution to find the mode (peak) of the distribution.
Main Output of Single Face Tracker
Real-time tracking and recognizing multiple faces in complex environments has the ability to provide security automation to large areas. Previous research has shown that few filter techniques paired with the traditional face detection methods.
