Synthesize of emotional facial expressions through manipulating facial parameters

By synthesize of emotional facial expressions through manipulating facial parameters, we aim to introduce facial emotion to a neutral facial image. For this, we perform a preprocessing process in which the face region is identified based on the skin color segmentation method. Then face is located with the connected area identification process. The feature points in facial region is examined, extracted and get stored. Then in the expression generation stage, we perform the expression generation algorithm. In this algorithm bilinear transformation is used with in the mesh warping technique to manipulate the facial parameters. Thus we could generate some standard set of expressions like happy, angry, sad, fear, surprise. Experimental result shows that the proposed system generates a realistic facial expression images. This work will offers a future research to develop precise degree of a particular expression, virtual human facial expression animation generation, image editing etc.
