In recent years, important advances have been made in the area of recognition of facial expression. Humans are better in various aspects like in the field of the recognition. But as automation is increasing day-by-day there is need of the efficient machine recognition system. So, there are lots of research going on to machine recognition. The need however to combine the two or more facial expression recognition techniques in a naturalistic context is clear, where adaptation to specific human characteristics and expressivity is required. It's because somewhere single facial expression recognition technique alone cannot provide satisfactory evidence.
