code for decoding image using quadtree partition

With the development in the image processing field a wide variety of filters have been developed. The quality of filters mainly depends on to which extent it is able to recover the degraded image so that it is as close as to the original image that is in other words, a filter that minimizes the mean square error is an appropriate filter for a particular application. Median Filter is such a kind of non linear filter which minimizes the mean square error to a large extent. A variant of a median filter “switching median filter” is simulated using C in this project.

STREAMS example illustrates the technique of streaming wave files with DirectSound. Implemented with C++ and Microsoft Foundation Classes (MFC)

avi视频捕捉，vc++实现，可以捕获图象后存为avi格式-avi video capture, vc realized, can capture images of survival after avi format

本代码用于两个视频文件的透明叠加显示，并可设置透明度。-The code for the two video files show a transparent overlay, and transparency settings.

参数pszSound是标识要播放声音的字符串。 参数hmod是包含声音资源的可执行文件的句柄，当设置了SND_RESOURCE时，它不为NULL,其它情况为NULL。 参数fdwSound作用之一是表明声音资源的来源，它是一系列值的组合，通过或运算连在一起，设置适当的值可以控制声音的播放效果。如：SND_LOOP表示循环播放，SND_SYNC表示同步播放，更具体可以参考M-parameters pszSound logo is to play the voice of the string. Parameters hmod includes voice resources of the executable file handle, SND_RESOURCE when installed, it is not NULL, NULL other circumstances. Parameters fdwSound role is one of the voices and the source, it is a series of portfolio value, or processing units, setting appropriate values can control the voice of playback. Such as : SND_LOOP said cycle broadcast simultaneously broadcast SND_SYNC said, can be more specific reference M

本源码的功能是对YUV420格式视频进行去隔行处理，处理采用的算法是自适应的去隔行算法，实验平台是进行Opencl 配置后的Visual Studio2008，Opencl 计算的特点是利用GPU进行并行编程计算，处理视频的速度相比CPU计算处理速度有大幅提高。学习本代码，将有助于迅速了解Opencl 的编程模型和GPU并行计算的原理，同时对视频去隔行也会有所了解。
