TDOA

初步的代码，只保存边界的声波逆时偏移 RTM

说明：  可在matlab软件上实现自适应阈值分割(Adaptive threshold segmentation can be realized)

本代码用matlab实现了图像的Jpeg编解码，使我的毕业设计，在这里与大家共享。(The code is implemented using matlab Jpeg image codec, so my graduation, and share here.)

小波学习资料 供初学者和小波爱好者参考用()

结合维纳滤波的小波降噪方法，滤波效果很好(Combination of Wiener filtering of wavelet noise reduction method, filter works well)

高光谱图像进行MNF变换，采用MAF评价图像的噪声；处理过程与ENVI软件中的完全一样。(MNF transformation of hyperspectral images, using noise MAF to evaluate the image.the process is exactly the same with ENVI software .)

图像的简单匹配程序，在左影像上点一点，然后使用相关系数法在右影像上进行全局遍历，找到相关系数最大的点，设为匹配的目标点。(Simple image matching program, the image on the left point a little, and then use the correlation coefficient on the right image globally traversal, find the maximum point of the correlation coefficient, to match the target point.)

使用选择式掩膜平滑方法进行数字图像的边缘提取(Select the type mask smoothing method using digital image edge extraction)

说明：  对图像进行伽马校正，可以有效提升图像 亮度和对比度，低于低照度图像现在小于1的参数，对于高亮度的图像选择大于1的参数可以有效调节图像亮度。(Gamma correction can effectively improve the brightness and contrast of the image. The parameters lower than the low illumination image are less than 1. For the high brightness image, the selection of parameters greater than 1 can effectively adjust the brightness of the image.)

基于加权最小二乘的滤波器。实现应用的例子。(weighted least square)
