fingerprint-OF-estimation

利用霍夫变换检测直线，园，椭圆，曲线，简单有效，用用方便(Using Hough transform to detect straight lines, park, oval, curve, simple, effective, easy to use with)

图像处理.最全的压缩编码与解码.非常值得学习(Image processing most complete compression encoding and decoding. Worth learning)

说明：  主成分分析算法提取特征值，使用KNN分类器，K值可调(principal component analysis)

1.支持多用户 2.支持自定义背景音乐，更个性化 3.可自定义浮动图片使留言本更漂亮(1. Support multi-user 2. Support for custom background music, more personalized 3. Customizable floating picture to make this message more beautiful)

很有用的彩色图像分割方法，经本人实验，绝对可靠(Very useful for color image segmentation method, by my experiment, absolutely reliable)

亚像素边缘检测的matlab代码，比一般的边缘检测代码精确(Sub-pixel edge detection matlab code)

说明：  结合Retinex和CLAHE图像去雾，Retinex有ssr，msr，msrcr。(Combine Retinex and clean image to remove fog)

先检测出椭圆，然后对椭圆进行椭圆拟合，画椭圆。(First detected in an oval, and then carried out on the elliptical ellipse fitting, painted oval.)

说明：  实现图像的清晰分割，效果明显,基于图像灰度-梯度构造的二维直方图，在此基础上计算目标与背景的二维Renyi熵(It can handle more types of images and get more accurate shape of the image edgee that pixels gradient information in combination with parameter of Renyi entropy which is adjustable)

很好的将lab空间中各颜色分量区分开，亲自使用过修改即可使用(It is very good to separate the color components in lab space.)
