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.

Compared with the traditional methods used in the image processing, this approach offers advantages of taking into account the correlation of the whole image, keeping fine details of image and avoiding the sawtooth effect and smoothing effect associated with traditional image interpolation techniques.

与图像处理中的传统插值算法比较，该算法通过提取图像的分形特征保持图像的全局相关性，更好地保持图像的细节信息，避免了传统插值算法引起的锯齿效应和平滑效应。

In order to study the relatively intensity of Zeeman effect split spectrum line, the quantum number distribution and the relatively intensity are presented in detail by the analysis of Hg(546.1 nm) spilt spectrum line in the external magnetic field; the image of coherence circle is obtained by CCD, and the intensity of image is analyzed, the relatively intensity of the spilt spectrum line by image disposed is close to the theoretical result. It is concluded that the phenomenon and rule of Zeeman effect can be analyzed by CCD image technology.
