Abstract (Summary of the Work)

We present a computer based approach which recognizes emotional facial expressions along with subtle micro expressions. Our system captures live video streams and recognizes both macro and micro expression at the same time. This procedure integrates the task where a set of frames is classified whether it contains micro expressions or macro expressions at first. Afterwards corresponding micro or macro expressions are further classified to its type. We have introduced Motion Magnification using Eulerian Video Magnification method to magnify subtle local motions that helps identifying types of micro expression. We have done extensive experiments on two publicly available data sets CK+ containing videos of posed macro expressions and CASME II containing videos of posed micro expressions. Using variants of LBP features such as Uniform LBP and Rotation Invariant LBP feature dimension is reduced by 80% compared to normal LBP based features that leads to reduction of response time and increases computational efficiency and results in effective classifier performance.
