this codes describe several kind of image filters

说明：  meanshift算法实现目标的跟踪，由视频序列文件中提取出第一帧，定义目标区域，进行跟踪，动态显示跟踪结果(meanshift target tracking algorithm, by the video sequence documents to extract the first frame, the definition of the target area, tracking, tracking the results of dynamic display)

说明：  带颜色恢复的MSR代码，可直接在MATLAB上调用。(MSR code with color recovery can be called directly on MATLAB.)

这是一个利用导数光谱分析的方法检测特征吸收波段的源代码，可供从事高光谱图像处理的朋友分享。(This is a use of derivative spectroscopy method of the characteristic absorption band of the source code, available to engage in high-spectral image processing share.)

matlab数字图象处理工具箱 包括imstack2vectors 霍夫变换等许多工具(imstack2vectors Hough transform matlab digital image processing toolbox includes many tools)

对一维信号的过采样函数，采用SINC插值的方法，可以使输出信号更加平滑。函数用法有说明，并附有简单程序进行验证说明。希望对有需要朋友有用! 有问题欢迎留言交流！(For the oversampling function of one-dimensional signal, SINC interpolation method is used. The usage of the function is explained, and a simple program is attached to verify the explanation.)

说明：  首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)

典型的一维kalman滤波原理程序，容易掌握！(typical one-dimensional Kalman filtering process easy!)

图像处理中ransac算法使用工具，同图复制篡改检测(The image processing algorithm ransac tool tamper detection with FIG copy)

BBO I类匹配角计算 通过修改相应的参数可以计算其他负单轴晶体的I类匹配角(BBO Class I match angle calculated by modifying the parameters can be calculated other negative uniaxial crystals Class I match angle)
