Recognition system based on skin color is main method of character detection of face and hand. This paper analyzed some common method of transformation of image enhance on the basis of YCbCr skin color model. A enhance method which is integrated exponential and logarithm transformation is proposed. And according to the shortcoming of fixed threshold, an automatic threshold algorithm with the fisher...
A new method based on Two-Dimensional Within-class Principal Component Analysis (2DWPCA) is proposed for face recognition in this paper. First, the within-class image scatter matrix of each class is calculated by using the training face samples in each class, respectively. Then, according to the within-class image scatter matrix of each class, the optimal eigenvectors of each class are computed, and...
