自编源码：读取 yuv 文件保存为Jpg图，实现视频文件的转化(Own-source: Read yuv files saved as Jpg map, realize the conversion of video files)

纯contourlet变换，已对工具包进行了修改，使之在分解重构时能显示子带系数。(Pure contourlet transformation toolkit has been modified so that when displayed in the decomposition and reconstruction sub-band coefficients.)

Jsteg算法实现基于JPEG图像的信息隐藏(Jsteg algorithm information hiding based on JPEG image)

图像的平滑函数，对指定区域的图像，并有门限值和魔板大小限制。(the smooth of a bmp image)

使用matlab对医学图像进行处理，不同去噪方法结果的对比。(matlab image nosing)

给予matlab的JPEG压缩程序，包含原始压缩图片，程序对灰度bmp图片进行JEPG编码，压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。(Given to the JPEG compression matlab program, contains the original compressed image, the program of the grayscale bmp picture JEPG encoded, compressed into a 0101 form of encoding. RBG color coded JPEG image into a first luminance Y and chrominance Cr, Cb, which uses the human visual characteristics is not sensitive to the color, reduce the number of color data to achieve compression. Take a variety of JPEG encoding, includes length coding (Run Length Coding) and Huffman (Huffman) coding, a high compression ratio. In the code before the data block, discrete cosine transform (DCT) and quantization, to retain a large low-frequency signal energy, discarding high-frequency signals in order to achieve compression.)
