水印攻击测试程序optimark。 这个比stirmark更全面测试水印程序，很好用(Watermark attack test program optimark. This more comprehensive test than stirmark watermark program, very good use)

粒子滤波器使用示例，用于跟踪效果好，用VC++实现(example of particle filter)

本程序实现图像LENA的压缩传感 程序作者：沙威，香港大学电气电子工程学系，wsha@eee.hku.hk(The procedure of image compression sensing process by LENA: Javert, University of Hong Kong Electrical and Electronic Engineering, wsha@eee.hku.hk)

这是SPAMS的原始代码，是稀疏表示的重要工具箱~(This is SPAMS original code, is an important toolbox sparse representation)

利用霍夫曼编码对图像进行编码及解码，计算霍夫曼编码效率(huffman encode and decode)

四种图像去噪程序，给原图像分别加上高斯噪声，椒盐噪声，乘性噪声，脉冲噪声后进行去噪，输出去噪后的图像(Four image denoising procedures, to the original image plus Gaussian noise, salt and pepper noise, multiplicative noise, impulse noise the Denoising output denoised image)

简单的介绍了基于matlab的QR码的识别，包括图像的预处理，图像定位，图像的识别等(This paper briefly introduces the recognition of QR code based on matlab, including image preprocessing, image positioning, image recognition and so on.)
