基于小波变换的使用SPIHT算法进行图像压缩，并对原有的算法进行优化(Based on wavelet transform using the SPIHT algorithm for image compression, and the original algorithm to optimize)

点云读取，旋转，平移，缩放，统统是包含全视图的各种视图的显示(Point in put)

指纹识别预处理，预处理包括图像增强，图像细化，寻找奇异点，细节检测(Preprocessing of fingerprint identification)

基于块匹配的稳像算法，包括演示视频，非常全面，希望对大家有帮助(Stabilization based on block matching algorithms, including a demonstration video, very comprehensive, we hope to help)

说明：  粒子滤波器matlab实现，用于实现目标检测算法(Particle filter matlab realized, for the achievement of Target Detection Algorithm)

Matlab图像处理,包含图像平滑、锐化等 图像平滑处理包含均值滤波和中值滤波 图像锐化处理包含拉普拉斯算子和Roberts算子、Prewitt算子和Sobel算子(Matlab image processing, including image smoothing, sharpening and other image smoothing with the mean filter and median filtering image sharpening with the Laplace operator and the Roberts operator, Prewitt operator and Sobel operator)

目前MATLAB里边对于多点计算仿射矩阵普遍采用RANSAC法，但是比较麻烦计算量也相对较大，通过最小二乘法来进行仿射矩阵的估计能够大大提高该效率，所以奉上自己在实验室写的仿射矩阵估计函数，来弥补matlab函数库在这方面的不足。(The MATLAB inside for calculating affine matrix commonly used RANSAC method, but more trouble calculation is relatively large, estimated by the least squares method to the affine matrix can greatly improve the efficiency, so give yourself in laboratory to write the estimated affine matrix function, to compensate for the lack of MATLAB Library in this area.)

基于matlab的ssim图像质量评价，验证还可以(Image quality evaluation)

伯克利图像小组提出来的图像分割评价指标：边界误差。(Evaluation of image segmentation. Image: Berkeley group boundary error.)

这是关于pca的文件，说明实现pca的降维(This is the file on pca, achieve pca dimensionality reduction)
