比较五种窗函数特性matlab程序：得到矩形窗、海明窗、三角窗、汉宁窗和布莱克曼窗图形。从仿真结果可知：矩形窗设计的过渡带最窄，但阻带最小衰减也最差。布莱克曼窗设计的阻带最小衰减最好，但过渡带最宽。-Comparison of characteristics of five kinds of window function matlab program: to be a rectangular window, Hamming window, triangular window, Hanning window and Blackman window graphics. From the simulation results we can see: the rectangular window designed for narrow transition zone, but the minimum stop-band attenuation is also the worst. Blackman window design of the stop-band minimum attenuation is best, but the transitional zone widest.

本程序提供了强大的图像处理功能，包括颜色变换、直方图及其均衡化、对比度变换、分割、轮廓提取、FFT/DCT、各种滤波等，能为图像处理研究者提供参考。-this procedure provided a powerful image processing functions, including color transformation, and histogram equalization. Contrast transformation, segmentation, contour extraction, FFT/DCT, various filtering, Image processing can provide reference for researchers.
