说明：  实现信号的小波分解，绘制小波不同尺度下的信号分解图形，同时去除噪声，实现信号的小波重构(The realization of the wavelet decomposition of signals, mapping at different scales of wavelet signal decomposition graphics, while removing noise, the realization of the signal wavelet reconstruction)

这是一个surf特征匹配matlab程序，里面有实例和测试图像(This is a surf feature matching matlab program, there are examples and test images)

读取一幅图像，对其进行DCT高通、低通滤波，输出处理后图像(Read an image, do the DCT high-pass, low-pass filtering, output processed image .)

基于统计算法的红外图像非均匀性矫正算法，场景类算法，实现实时校正(IRFPA NUC)

使用规定分布生成空间随机噪声，可以选择噪声类型和参数。(Using the prescribed distribution to generate spatial random noise, we can choose noise types and parameters.)

说明：  权重自适应图像去噪，根据形态学。效果还行(Weight adaptive image denoising)

基于小波包变换的去噪处理 全局阈值去噪图像 对图像进行平滑处理以增强去噪效果（中值滤波）(Denoising based on wavelet packet transform global threshold denoising image smoothing image enhancement and denoising effect (median filtering))

matlab 写的提取图像亚像素边界的程序，和Canny算子有比较，里面有两张示例图像！(matlab write the image to extract sub-pixel border procedures, and the Canny operator have more, there are two examples of images!)

将一幅图像以jpeg的形式进行压缩，对初学者很有用(Jpeg form of an image compression, very useful for beginners)

灰度共生矩阵 图像纹理特征提取 matlab语言编写(GLCM texture feature extraction matlab language)
