As everyone knows nature exists a lot of colors similar as skin color, such as sand, sand beach, soil, stone, cement road, wood, bole, filemot leaves, and so on. The above mentioned things are similar to skin color and exist largely in our images. So they bring many difficulties to detect human face color. And the problem hasnpsilat been solved completely.

In order to detect more reliably skin color for color facial image with complicated background, we have presented a detection method based on uniting YCgCb color space with YCgCr color spaced. There exist many colors in nature that are similar to skin color, such as sand, sand beach, soil, stone, cement road, wood, and so on. The things mentioned above are similar to skin color and create many difficulties...
There exists an enormous gap between low-level visual feature and high-level semantic information, and the accuracy of content-based image classification and retrieval depends greatly on the description of low-level visual features. A novel method of mapping semantic gap is presented in this paper, which first extracts color and texture features from images after adaptive thresholding segmentation...
