The diagnosis of disease with the aid of computer programs has been developing more and more in recent years. This paper presents an approach which is based on frequency technique for the objective quantitative analysis of facial paralysis. In this method, limited-orientation modified circular Gabor filters (LO-MCGFs) are used to enhance the desirable frequencies in images. Then, features are extracted...
Facial paralysis, the majority of which is idiopathic, causes loss of facial movement of one side. It is important to construct a facial expression databases to quantitatively evaluate this condition for early treatment of facial paralysis. Generally, the existing human facial expression databases are built using healthy volunteers for face recognition or expression recognition. In this paper, we...
Image warping and morphing are important visual effect tools in entertainment industry and other research fields. We developed a prototypical automatic facial image manipulation system (AFIM) for face morphing and shape normalization (warping). In our AFIM system, there are two main functions: (1) warping a facial image to a target image (face shape normalization), (2) generation of inter- or intra-personal...
