傅里叶梅林变换参考代码

Hu的七个不变矩在图像处理，尤其是特征提取方面是很重要的一个概念。本代码实现了图像的7个不变矩的计算和输出。( Hu s 7 moment invariants is significant in image processing,especially in feature seletcion. This code calculate them.)

采用色温估计法做的白平衡操作，之前是打算用到水下处理的，当然这个算法和PS的白平衡比有点LOW，可是这个能够matlab，有一定用途(The white balance operation using the color temperature estimation method was intended to be used underwater. Of course, the white balance ratio of this algorithm and PS is a little LOW, but this can be used in matlab.)

使用vtk库开发的volume程序，主要用于建立多边形面片，用于演示三维体的算法。(Developed using VTK library volume procedures, set up primarily for polygon surfaces for the presentation of three-dimensional body algorithms.)

基于mfc的车辆检测程序，利用帧间的变化来检测，适合初学图像的同学学习(Mfc-based vehicle detection program to detect changes in the use of frames, suitable for beginners to learn the image of the students)

基于混沌的音视频加密系统的设计与实现论文；对混沌学习有帮助(Design and implementation of the chaotic audio and video encryption system)

说明：  对于一些图像来说，常用的边缘检测算法有时候无法设立合适的阈值将它们的梯度较小的模糊边缘检测出来。为了解决这个问题，有两种解决方法：将图像方差标准化，拉大模糊边缘的梯度值，或通过设置sigmoid函数，将像素所在区域的信息传递到梯度值中去，对其进行调整，就能找到合适阈值，有效地将模糊边缘提取出来。本程序把这两种算法实现并与与传统算法进行了比较。(For some images, the commonly used edge detection algorithm sometimes can not be an appropriate threshold for the gradient of their smaller fuzzy edge detected. To solve this problem, there are two solutions: the image variance standardization, widening the fuzzy edge of the gradient value, or by setting the sigmoid function pixel region to disseminate the message to the gradient values to adjust, on the can find a suitable threshold, effectively extracted fuzzy edge. This procedure of these two algorithms with the traditional algorithm.)
