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.

本篇论文比较详细地论述了遗传算法的基本理论、方法，指出了算法的研究现状，由于图象分割的重要性，提出了两种基于遗传算法的彩色图象分割方法，即阈值曲面分割方法和最佳熵阈值分割方法，通过VC++6.0编程得到了实验验证，比较了两种算法的性能，证明遗传算法完全适用于图象的优化问题。

In order to distinguish these two types of transitions, a state recognition method is introduced. We firstly propose a variable contact set in which the contact points on the robot body are defined to represent the alternation of the contact states logically. Then, by predefining thresholds for the contact forces, the state transition can be well recognized.3 As another research topic, the local tracking control according to the pre-acquired state transition trajectories plays an important role in realizing the non-regular motion for the humanoid robot.

在状态转换识别方法上，本文提出了接触点集合的概念，对接触状态的变化进行逻辑上的表达；再结合接触点集合的变化情况，通过设定接触力阀值来实现对状态转换的识别。3根据给定的状态转换轨迹进行局部的跟踪控制，是本文实现类人机器人非规则运动的另一个重要研究内容。
