In this paper, a novel approach is presented based on a dichromatic reflection model to detect and correct highlighted skin pixels in the TSL(tint-saturation-luminance) color space.

This paper discussed the basic conception of vegetation bidirectional reflectance distribution function and its physics meaning,and carried out a brief argumentation on the theory of existed several vegetation bidirectional reflected model: geometrical optics model,muddy medium model,mixing model and computer simulation model,and compared the characteristic of all kinds model.

Important aspects of skin color detection are discussed, including color space selection, static and dynamic skin color modeling, skin reflection models, and visual a.

According to double color reflection model,this paper develops the relationship of three channels of color im-age,we find that color image may process one color channel firstly,and then produce a scale-matrix,the other color channel may process by the scale-matrix.
