Classification of Sentiments through Rough Fuzzy Approach

Facial expressions being a part of gesture is a biggest asset for non verbal communication. We are using facial expression of current image as a context to hand gesture which again acts as a context to the next image linking the images in a video to extract unstable sentiments. Facial expression is not precise as beauty. It’s a vague concept; hence we have used Rough set. But some facial expressions are universal hence fuzzy set as they definatley belong to that membership set. Ther may be hidden context to every facial expression. We have introduced the intensity levels of facial expressions through fuzzy level factors which improves results in extracting mixed feelings. Bharat Natyam, a renowned Indian Classical Dance is taken as Dataset for test verification.
