机器视觉领域 Harris 角点检测的matlab实现 压缩包内附有一张非常适合用于测试的图片01.tif-Harris corner detection in the field of machine vision matlab achieve compression package included a very suitable for testing the picture 01.tif

zlib高压缩算法，已裁减，内有测试代码。可以压缩一张图片。测试一下压缩效果-zlib compression algorithm for high has been cut, there is test code. A picture can be compressed. Compression test results

利用pcat提取特征值并完成降维，进而通过测试一张图片到特征脸的三阶距离完成人脸识别 言语表达不清的地方请见谅咯(we used the pca to make a facerecognition.)

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded m
