梯度倒系数实现背景抑制,提高小目标检测的信噪比(reversing Coefficients gradient background suppression, and enhance the signal-to-noise ratio target detection)

基于ransac的椭圆检测，对于一组随机的椭圆点，可以得到椭圆参数，检测精度高。(Based ransac ellipse detection, for a group of random elliptic points, you can get an ellipse parameters, high detection accuracy.)

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)

图像降噪、贝叶斯估计、盲源降噪,采用盲源方法进行噪声估计，再进行贝叶斯非局部均值降噪(Image denoising, Bias estimation and blind source noise，The blind source method for noise estimation, then the Bayes non local mean noise reduction)

生成相机标定所用的方格图，用于相机标定使用(Generates the grid chart used to calibrate the camera)

说明：  扫描文件夹，通过文件大小和创建时间判断图片文件是否重复，并分类和重命名(Scanning folders to determine whether image files are duplicated, categorized and renamed by file size and creation time)

何凯明暗通道先验法进行单幅图像去雾的实现。 严格按照每一步编程。步骤清晰，代码易懂，更改图片路径后便可执行。(Make a single image to achieve HE dark fog channel priori method. In strict accordance with each step programming. Step clear, easy to understand code, change the image path after the executable.)

小波分析的各种尺度分解包括单尺度分解，多尺度分解以及小波包分解及重构，小波分解重构精简(All kinds of scale decomposition of wavelet analysis include single scale decomposition, multi-scale decomposition, wavelet packet decomposition and reconstruction, and wavelet decomposition and reconstruction.)

粒子滤波matlab程序，主要是扩展的卡尔曼粒子滤波(Particle filter matlab program, mainly extended Kalman particle filter)

数字图像处理中对分类器优劣的判定常用的ROC/ACU源码。希望对你有用。(The ROC/ACU source code commonly used in the determination of the quality of the classifier in digital image processing. I hope useful to you.)
