小波包分解，求能量程序，，对小波包的了解掌握都很有用，希望对读者游泳(the wavelet packet decomposition and energy distribution )

说明：  本文简要回顾了OpenCV的发展，介绍了OpenCV的各种应用，并详细分析了其中一些应用的原理、算法和代码，最后还介绍了一些关于OpenCV的最新研究进展。(This paper reviews the development of OpenCV, OpenCV introduces a variety of applications, and application of a detailed analysis of some of the principles, algorithms and code, and finally describes some of the latest research on the progress of OpenCV.)

带运动估计的时域滤波，一种基于小波的运动估计方法，可以有效的去除视频流的帧间冗余。与传统的帧参考模式的运动估计相比，没有错误漂移现象。内含编码器和解码器。(Belt Movement estimated time domain filtering, a wavelet-based motion estimation methods, can effectively remove the inter-frame video stream redundancy. With the traditional frame of reference than the motion estimation, no errors drift phenomenon. Intron encoder and decoder.)

主成分分析的三种方法，一种是自编程序，一种是princomp函数,一种是pcacov函数(Three principal component analysis, one is self-programming, one is princomp function, a function is pcacov)

本解码器类支持普通jpeg文件格式，这也是目前大多数jpeg文件所采用的格式，此格式主要特点是数据精度为8位，采用Huffman编码的普通DCT帧（不支持扩展串行和递进模式及数学编码）。本解码器类的 IDCT算法采用三种模式，分别是浮点解码、定点整数解码和定点整数MMX优化解码，您可根据具体情况选择。(The decoder class support common JPEG file format, which is currently the most JPEG files in the format and the main characteristics of this format is data for 8-bit precision, using Huffman coding DCT common frame (does not support extended serial and progressive model and arithmetic coding). The decoder of the IDCT algorithm uses three modes, respectively, floating-point decoding, fixed-point integer decoding and fixed-point integer MMX optimization, you can choose according to the specific circumstances.)

问题：找出一个短字符串在一个长字符串中的精确匹配。 要求：基于BWT压缩和FM索引技术的序列匹配，用Burrows-Wheeler transform算法解决该问题。(Problem: find the exact match of a short string in a long string. Requirements: BWT-based compression and indexing techniques sequence matching FM, with the Burrows-Wheeler transform algorithm to solve the problem)

这是一个阈值分割的小例子，利用阈值分割把原始图片转化为二值图像和灰度图像。(This is a small example of a threshold segmentation using thresholding the original image is converted to binary and grayscale images.)

提取并显示鼠标所在图像点的颜色，C++精选学习源码，很好的参考资料。(To extract and display the image color, select learning C++ source code, a good reference.)

鱼眼图像校正并将校正后的图像转换成鸟瞰图，即俯视图，纯C代码，没有调用其它库(fish eye image correction,then change it to bird s eye view)

说明：  边缘检测算法 速度快 你一定会满意的。以前是要收费的。现在免费给你们。 源码经过测试真确无误。 (edge detection algorithm faster you will surely satisfied. Prior to the charges. Now free to you. Source tested truthful.)
