基于802.11a协议的OFDM程序 matlab，很有用哦(OFDM-based 802.11a protocol procedures matlab, oh, very useful)

说明：  缺陷识别m文件，对缺陷图像进行中值，小波去噪，利用数学形态学方法提取二进制图像轮廓，并计算裂纹等缺陷的面积和周长(M file defect identification, the value of the defect in the image, wavelet denoising, using mathematical morphology to extract the binary image contour, and calculates the cracks and other defects in the area and perimeter)

matlab自带的很好用的kmeans算法程序，已经验证通过，(matlab kmeans algorithm, matlab kmeans algorithm matlab kmeans algorithm procedures)

matlab数字水印 通过这个程序可以给原图象加上水印 但不可以提取！(Matlab digital watermarking through this procedure can be added to the original image watermark but not extract!)

用MATLAB对图像进行基本的处理，包括读取、均衡化、不同方法显示、数据类型对显示方式的影响等基本操作，非常适合初学者(Using MATLAB to perform basic image processing, including reading, equalization, different methods of display, data types on the display of such basic operations, is suitable for beginners)
