计算一幅图像的熵，matlab编程文件，任意读取一幅图像，计算信息熵(Calculate the entropy of an image)

说明：  利用图象边缘特征的基于豪思道夫距离的景象匹配算法，匹配速度要比基于灰度的算法高好几个数量级(use of the images on the edge of Ho Sze-Astoria distance from the scene matching algorithm, speed matching gray than the algorithm based on several high-volume)

scikit-image: Image processing in Python：Python编写的图像处理程序，可直接调用，是学习python图像处理的很好参考。(scikit-image: Image processing in Python：Image processing program written in Python, can be called directly, is to learn Python a good reference to the image processing.)

说明：  使用PSTD计算方法实现的3维时间反转镜像技术算法，可用于声学及电磁学成像(A Time Reversal Mirror Algrithm devopled by the 3 dimensial PSTD numerical method, it can be used in acousic and electromagnitic imaging field)

说明：  其可以直接绘制vaspkit生成的能带图，直接调用即可，可以批量生成能带图(It can directly draw the band diagram generated by vaspkit)

说明：  用平方根算法进行矩阵的优化，以便使用卡尔曼滤波获得精确的值(kalman filter and pingfanggen method ，using it can obtain accurate value )

图像配准，首先实现了简单的图像预处理，然后根据两种不同的配准准则，互信息和边交互方差作图像配准(Image registration, first of all to achieve a simple image pre-processing, and then two different registration criteria, mutual information and edge interaction variance for image registration)

此程序为摄影测量的一个小环节，主要功能是求解影像畸变差，可根据相机内参数求解，简单实用(This program is a small part of photogrammetry, the main function is to solve the differential image distortion can be solved according to the camera parameters, simple and practical)
