A formal facial image compression algorithm is proposed in this paper. Object segmentation techniques is used to locate the facial region firstly. An adapted version of the original Viola-Jones face detector is used to locate eyes and mouth. The position of chin is estimated and then checked according to the curve in the edge image. Secondly, the background is reassigned to decrease unvaluable information...
In this paper, we solve the searching problem by high level features used by sign language recognition. Firstly, we find the face in video frames that has complex background, and then we find the left sign and right sign in specific areas. By computing the signs' length, position, velocity, acceleration, Fourier figure descriptor and etc, we generate the signs' dynamic features. Consequently, we segment...
This paper presents a style transfer algorithm of caricature. Rather than transferring texture from one image to another globally, we introduce an interactive tool for local texture transfer of caricature. As the segmentation algorithm is not very satisfactory for complex case of human face and the caricature, we use a brush by which the user draws some strokes on the source and target images to indicate...
The data in face images are distributed in a complex manner due to the variation of light intensity, facial expression and pose. In this paper the Kernel Principal Component Analysis (KPCA) is used to extract the feature set of male and female faces. A Gaussian model of skin segmentation method is applied here to exclude the global features such as beard, eyebrow, moustache, etc. both training and...
