Arnold置乱变换的matlab代码，函数形式，做数字水印经常用到。(Arnold scrambling transform matlab code, functional form, so often used in digital watermarking.)

标准DCF的仿真代码，只包括基础接入机制(DCF standard simulation code to include only basic access mechanism)

要求设计一个基于颜色直方图的图像检索系统。该系统能够实现对图像的检索功能，例如，在一万幅图像中搜索出与检索图像相似的图像，依相似程度的大小显示出来。最后用查全率和查准率对系统进行评估。(To design a color histogram based image retrieval system. The system can realize the image search function, for example, a square image search and retrieval of an image similar to the image size according to the degree of similarity is displayed. Finally, recall and precision to evaluate the system.)
