说明：  基于活动轮廓模型的图割算法，实现图像的高效分割！非常好的代码。希望帮助大家！(Graph cuts based active contours which is used for image segmentation.Excellent source code!)

说明：  1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换，并显示其频谱，用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。（提示：显示频谱时，可以先对频谱取对数，这样可以压缩动态范围很大的频谱，获得更好的显示效果）(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))

CVPR2013中出现的一种显著性特征检测算法，该算法用于模拟人眼视觉识别过程，提取图像中的显著性特征借后期目标对象的检测跟踪等使用，该算法(Context-Aware Saliency Detection。matlab implementation of an classical saliency detection alrogithm,which imitate our recognition process of eyes)

Lee滤波器，具有很好的去噪效果，结合各种小波，可以有效去除SAR图像噪声。(Lee filter, has a good de-noising effect of combination of wavelet can effectively remove the SAR image noise.)

说明：  Impulse response, system response, for signal processing

强化细节的自适应直方图均衡化,分块的算法，可以自动调节窗口大小进行局部增强。()

图形处理，Visual C++数字图像识别技术典型案例源代码 5(Graphics processing , the Visual C++ digital image recognition technology to a typical case of source code 5)

matlab写的对图像进行简单的伽马校正，代码中给出了两个例子(matlab write simple image gamma correction, the code gives the two examples)

基于SUSAN特征检测算子的边缘提取，添加图片即可运行，可自行根据图片特征设置参数得到较好的边缘检测效果(Edge detection feature extraction SUSAN operator, add images to run, you can set your own parameters to get a better edge detection based on image characteristics)

很好的图像分割软件，内有全部源码，对研究matlab图像识别处理很有帮助(good image segmentation software, comprising all the source code, the study Matlab image recognition processing helpful)
