肺结节检测 ，包括肺部粗提取，肺结节提取，特征提取，与特征分析，以及最后的分类！( U80BA u7D3 u53D0 u53D0 u53D0 u53D0 u53D6 uvd0 U4E0E u7279 u5F1 u5206 u6790 uFF0C u4EE5 u53CA u6700 u540E u7684 u5206 u7C7B uFF01)

完成流程编码和huffman编码，适合做图像编码的熵编码，只要调整接口就好。(Complete the process encoding and huffman coding, image coding suitable for entropy coding, as long as the adjustment of the interface is like.)

说明：  计算机图形学ppt， 介绍计算机图形学基础(Computer graphics ppt, introduced the basis of computer graphics)

说明：  实现直接序列扩频水印的嵌入与提取。基于待嵌入消息生成二进制水印序列,生成扩频码，用消息序列调制生成水印序列。依次处理灰度图像的每一个载体图像像素，根据相应位置 水印序列完成嵌入修改。(Realize the embedding and extraction of direct sequence spread spectrum watermark. The binary watermark sequence is generated based on the message to be embedded, the spread spectrum code is generated, and the watermark sequence is generated by message sequence modulation. Each carrier image pixel of gray image is processed in turn, and the embedding modification is completed according to the corresponding position watermark sequence.)

snake算法的多种实例，包括ballon，distance等共计8个m文件(snake algorithm many examples, including ballon. Total distance, and other documents 8 m)

改进的剪切波变换，用于图像处理，分解层数多，运行速度快(Improved shear wave transform for image processing, decomposition of many layers, fast running speed)

小波软阈值去噪的MATLAB代码,输入噪声均值就可得出含噪图像和去噪图像,同时得出峰值信噪比.(Wavelet soft-threshold denoising of MATLAB code, the mean input noise with noise will get the images and de-noising images, peak signal to noise ratio obtained at the same time.)

说明：  同态滤波利用去除乘性噪声(multiplicative noise)，可以同时增加对比度以及标准化亮度，借此达到图像增强的目的。(Homomorphic filtering can increase contrast and standardize brightness simultaneously by removing multiplicative noise, so as to achieve the purpose of image enhancement.)
