matlab_声音信号FFT

说明：  一个从网上找来的屏幕截取代码，需要的就看看吧(A screen from the Internet and got the interception code, need to look at it)

说明：  对灰阶图像进行大气湍流滤波，使图像达到需要达到的效果(The atmospheric turbulence filtering is applied to the gray scale image to achieve the desired effect)

关于边缘检测、图像分割matlab源程序，Prewitt算子、LoG算子检测、阈值分割、水线阈值法分割、文字和非文字区分等(on edge detection, image segmentation Matlab source, Prewitt operator, Getting Operator detection, thresholding segmentation, subaqueous threshold method segmentation, textual and non-textual distinction)

基于matlab实现对 图像的亮度提取 以及对其亮度均匀性进行评估！(Matlab-based implementation of image brightness, as well as its extraction to assess the uniformity of brightness!)

说明：  对图像进行中值滤波，代码调试通过，附有lena图像(The image is filtered by median filter, the code is debugged and passed, and the Lena image is attached.)

使用vs2012+opencv2.4.5做的人脸检测代码，可以实现对静态图像上人脸的检测(Use vs2012+ opencv2.4.5 do face detection code, you can achieve detection of static images of the human face)

稀疏低秩去噪的MATLAB代码，包括OMP算法与KSVD算法(Sparse low rank denoising MATLAB codes, including OMP algorithm and KSVD algorithm)

关于做人脸检测的时候所用到的Haar-like特征国内的文献讲的不是很详细，大家可以参考一下这篇文献，比较有价值的啊(human face detection of the time when used in the Haar- like characteristics of the domestic literature stresses is not very long Fine, we can refer to this document, the more valuable ah!)
