给定一幅图象，输出其直方图； 通过对话框给定一个线性变换函数，实现图象的灰度拉伸； 实现对图象的均衡化。 读入任一幅图象，输出显示灰度拉伸的图象和均衡化后图象。 -Given a picture，output the ZHIFANG styles

图像自相似性计算。基于全局的图像自相似性计算的目标检测- Global and Efficient Self-Similarity for Object Classification and Detection From the methods in [1] this code allows to compute self-similarity hypercubes (SSHs). These SSHs can be obtained from a prototype as
