Code for make histogram of image

图像的反卷积 去卷积复原 效果还不错，欢迎下载(image deconvolution image restoration)

采用的是基于弦中点的hough变换椭圆检测算法，大家可以在百度上搜这篇论文，由于不是用的标准hough变换的算法，所以运行速度还不错(Used is based on the midpoint of the chord hough transform ellipse detection algorithm, we can search on Baidu paper, because the algorithm is not used in standard hough transform, so the speed is also good)

说明：  二进小波变换的图像增强,matlab代码(Dyadic wavelet transform image enhancement, matlab code)

本文提供了两种方法计算二维最大图像信息熵(This paper provides two methods for computing two-dimensional maximum image information entropy)

说明：  利用matlab对已知多对控制点的情况下进行两张图像校正，该算法能够取得较好的结果(Using matlab to correct two images when multiple pairs of control points are known.The algorithm can get good results.)

包含完整的SVM算法，下载即可使用。其中包括数据集和完整的算法结构，算法结构包括数据清理、核函数升维以及SMO优化算法，可以较好实现数据非线性分类。(Contains the complete SVM algorithm and download it for use. Including the data set and the complete algorithm structure, the algorithm structure includes data cleaning, kernel function upscaling and SMO optimization algorithm, which can better achieve nonlinear data classification.)

本程序主要实现暗背景下含高斯噪声的光斑滤除噪声，实现光斑中心提取。采用了sobel算子和梯度倒数加权滤噪、最大类间方差法（Otsu）确定阈值、质心法提取光斑中心坐标。(The program is mainly realized under a dark background Gaussian noise spot containing noise filtering, to achieve spot center extraction. Using sobel operator and gradient inverse weighting filter noise, Otsu method (Otsu) to determine the threshold, the center coordinates of the spot centroid extraction.)

这个压缩包中包含了巴特沃斯滤波算法的高通和低通两款代码，同时还有几篇巴特沃斯算法的文章，记录了关于巴特沃斯算法的一些应用领域。(This compressed package contains the code of two of the high-pass and low-pass Butterworth filter algorithm, at the same time, there are few Butterworth algorithm articles recorded Butterworth algorithm applications.)

将matlab处理得到的三维矩阵转化为envi软件可读取的数据格式raw(change the 3-D data from matlab to the raw form ENVI can read)
