图像处理的空域滤波增强部分程序代码的编写(Spatial filtering of the image processing, enhanced part of the program code is written)

daisy是08年新提出来的特征描述符算法，常用在图像匹配等领域中。文件包含算法的PDF文档和算法提出者编写的相应matlab程序，大家可以根据自己的需要来利用。(A Fast Local Descriptor for Dense Matching，2008.)

用基于稀疏表示和KSVD字典学习去噪方法在对数域对SAR图像抑斑，本方法相对于一些经典的SAR图像抑斑方法，抑斑效果大大提高。(Based on the sparse representation and KSVD dictionary learning denoising method in the logarithmic domain，we despeckle SAR image, compared with some of the classic SAR image speckle suppression method, this method is much more effective.)

说明：  对加载的图像进行灰度处理，简单处理matlab程序，效果不错，利于后面对图形进一步加工处理(Gray-scale processing of loaded images)

用于高光谱图像处理的端元提取，PPI方法能有效提取端元光谱。(HYPERPPI Performs the pixel purity index (PPI) algorithm Performs the pixel purity index algorithm for endmember finding.)

说明：  BCS代码稀疏重构Lena.bmp图像，包中含有代码和图片本身，题主给了一定注释，便于CS初学者学习(BCS code sparsely reconstructs Lena. BMP image. The package contains code and image itself. The theme is given a certain comment, which is convenient for CS beginners to learn.)

最新图像轮廓透明度计算算法。 发表在今年的计算机视觉会议(latest image contours transparency calculation algorithm. Published in this year's Computer Vision Conference)

一幅大小为256×256的256级灰度图像（每像素8bit） 如果图像的各个像素之间是统计独立的，求该图像的信息熵 -离散无记忆信源 如果图像的各个像素之间不是统计独立的，求该图像的信息熵 -图像像素的概率分布模型(A 256 gray scale image (8bit per pixel) with a size of 256 x 256 If each pixel of the image is statistically independent, the information entropy of the image is calculated Discrete memoryless source If each pixel of the image is not statistically independent, the information entropy of the image is calculated Probability distribution model of image pixels)

matlab实现的直线检测方法，主要为hough变换，包括图片及实验结果(Matlab implementation of the line detection method, mainly for the Hough transform, including pictures and experimental results)

RGB颜色空间转换为 YCbCr 和HSV空间，自己编写的matlab 代码，希望对打家有帮助。(RGB color space is converted to YCbCr and HSV space, have written matlab code, want to combatants spar in home help.)
