图像处理

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)

中值滤波在图像处理中占据很重要的地位，本代码是加权中值滤波处理源码。希望对大家有用。(Median filter in image processing occupies a very important position, the code is weighted median filter processing source. Hope to be useful.)

语音特征提取代码，提取mfcc和lpcc。(Speech feature extraction code, and extract mfcc lpcc.)

SIFT 尺度不变特征提取算法 可参考可运行有测试图片(SIFT with test picture and it can work well)

sar图像变化检测 基于减法代码 比较两幅图片的细微差别(sar image change detection code based on subtraction of two pictures comparing the nuances of)

说明：  我是一个图象处理的初学者,用MATLAB语言编写了一些内部的函数,实现了图象处理的功能,比如entropy,laplician,otsu,top-hat等(image processing is a beginners MATLAB language some internal functions, achieving image processing functions, such as entropy, laplician, Otsu, top-hat, etc.)

该函数是用于计算峰值信噪比和信噪比的程序(it can be used to calculate psnr and snr)

说明：   针对雾天下拍摄图像的退化现象，远景部分是一块灰度分布比较集中且接近天空亮度的区域，而近景部分可以分辨，其灰度分布比较分散。提出了一种基于遗传算法阈值分割的雾天图像增强方法；该方法首先用遗传算法求出近远景的分割阈值将图像分割[1]出来，然后对两个部分分别进行清晰化处理。(make the picture clear)

灰色预测模型matlab,灰色模型GM(1,1)程序二次拟合和等维新陈代谢改进预测程(Matlab of gray prediction model, gray model GM (1,1) procedures for the second fitting and the same dimension metabolism to improve the forecasting process )

IMAGING 工业相机图像灰度特征处理源代码，文件源码中集成了三方组件，非常有价值(IMAGING industrial camera image grayscale image processing source code, the source code to integrate the three party components, very valuable)
