语音增强算法，谱减法、小波变换以及数学形态学等的语音增强算法针对信噪比、语谱图、去噪情况，分析比较(Speech enhancement algorithm, spectral subtraction, wavelet transform and mathematical morphology speech enhancement algorithm for signal-to-noise ratio, the spectrogram denoising situation analysis)

图像处理,matlab文件，利用SURF进行图像拼接，完成图像配准(Image processing, matlab files, image stitching using SURF, image registration completed)

说明：  内含多种图像去噪的方法，包括高斯，椒盐噪声等问题(Contains a variety of image denoising methods, including Gaussian, salt and pepper noise and other issues)

说明：  直方图均衡，图像去雾处理，是把原始图像的灰度直方图从比较集中的某个灰度区间变成在全部灰度范围内的均匀分布。直方图均衡化就是对图像进行非线性拉伸，重新分配图像像素值，使一定灰度范围内的像素数量大致相同。(Histogram equalization, image processing to the fog, is the original image histogram to a gray scale from the more concentrated into the full range of uniform distribution within the gray area. Histogram equalization is that the image is non-linear stretch, re-distribution of the image pixel values, so that a certain number of pixels within the gray area roughly the same.)

MTF计算程序，图像源需为倾斜边缘，能快速计算不同倾斜边缘的MTF曲线。(MTF calculation procedure，Sequence image source need for inclined edge，Can quickly calculating different inclined edge of MTF curve. )

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)

这是一个扫描线种子填充算法的程序，这个程序的演示效果不错(This is a scan line seed fill algorithm program, this program demonstrates good results)

使用matlab来实现图像的处理，比如直方图均衡化等等(Using matlab to achieve image processing, such as histogram equalization)

一种新的改进的LBP特征提取方法，采用多块比较的方法(a new LBP feature extraction method)

基于dwt的数字图像水印技术的matlab源代码。包括嵌入和提取，效果不错。(Dwt-based digital image watermarking technique matlab source code. Including the embedding and extraction, good results.)
