以此为基础提出了小波边缘检测中的自动阈值选取算法，分别用灰度图像和彩色图像作实验，实验结果证明了这种算法具有较强的自适应性和较好的提取效果。
Algorithms of video segmentation that are good adaptive character and real time are crucial to the final mpeg 4 coding products there exist the contributions in this dissertation as follows obtaining the edge of video objects is crucial to the video segmentation , author researches the features of human being visual , especially giving a description of mach band that is usually used in the image processing , and builds a model of mathematics , researching the mach band of color image
( 1 )视频分割的关键是获得视频对象的边界，边缘检测很重要,本论文以人类的视觉系统的特性为出发点，对图像处理中经常应用的马赫带现象进行了详尽的分析并进行了数学建模，研究分析了彩色图像的马赫带现象。在对马赫带图像分析的基础上，得出了人类视觉系统对图像边缘能识别的最小灰度差和彩色差曲线。
