beginig : image processing using LENA_color

实现了对误拍角度的矫正，基于轮廓提取以及旋转矩阵变换实现图像错误识别和矫正(It realizes the correction of misalignment angle, and realizes image error recognition and correction based on contour extraction and rotation matrix transformation.)

较简易的视频目标跟踪算法，有需要的朋友可参考(Than simple video target tracking algorithm, there is a need to refer to a friend)

使用光流法对运动目标进行估计，要使用opencv一起实现。效果还不错(Using optical flow method to estimate the moving target, to use opencv implemented together. Results were pretty good)

基于arnold变换加密图像（带解密的代码），缺点是具有周期性(Encryption based on Arnold transform (with decryption code), the disadvantage is cyclical.)

说明：  自相关算法,用于图像处理方面，可以用来处理模糊的图像(Autocorrelation algorithm, for image processing, can be used to deal with blurred images.)

说明：  Hu的七个不变矩在图像匹配检索中适用广泛。本代码仅计算图像间Hu的七个矩的D2大小，直观的了解Hu矩的应用(seven moment invariants in image retrieval in the application of broad match. Only the calculation of the code between the image of the seven Hu moments D2 size, intuitive understanding of the application of Hu Moment)

说明：  用于图像处理的图像降噪领域，有需要的可以自己进行下载。(In the field of image noise reduction for image processing, you can download it yourself if necessary.)

利用汉宁窗设计Ⅰ型数字带阻滤波器,通过Matlab实现。(Band Reject Digital Filter based on HanningI though Matlab.)

说明：  K均值作为图像分割的经典算法，新手必学算法。利用K均值进行图像分割，关于分类个数可以进行人为设定。(As a classical algorithm for image segmentation, k-means is a must-learn algorithm for beginners. The k-means is used for image segmentation, and the number of classification can be set artificially.)
