阈值迭代分割图像，可以为研究迭代法朋友们提供一定帮助。(Iterative image segmentation threshold can be friends for the study iterative methods provide some help.)

Kernel Principal Conponent Analysis 特征提取(Kernel Principal Conponent Analysis feature extraction)

基于MATLAB 6.x开发，通过鼠标点击拖拽可以画出带箭头的线段。(ARROW may be called with a normal argument list or a property-based list. ARROW(Start,Stop,Length,BaseAngle,TipAngle,Width,Page,CrossDir) is the full normal argument list, where all but the Start and Stop points are optional. If you need to specify a later argument (e.g., Page) but want default values of earlier ones (e.g., TipAngle), pass an empty matrix for the earlier ones (e.g., TipAngle=[]).)
