In this thesis, the theories and methods of GA are analyzed in detail , the trend of GA in recent times is briefly discussed. Because of the importance of image segmentation, two methods of color image segmentation based on GA are proposed. One is the surface of thresholds image segment method, the other is entropic threshold method. Two algorithms are realized through VC++ 6.0. After that, we compare the characteristics of two algorithms and prove that GA can be very well applied to solving image optimal problems.
