解决Opencv高低版本不兼容问题

目前OpenCV版本已更新到2.4...由此出现了一系列问题，解决如下：

1、cxcore.h等头文件找不到：

法一、将opencv1.0中的各种.h或者.lib文件拷到opencv2.3.1对应include/library的路径的文件夹下。

e.g.   Cannot open include file: 'cxtypes.h': No such file or directory

像这种情况，在opencv1.0中又搜索不到的，果断把#include"cxtypes.h"删掉，其他问题慢慢解决。

2、CvFilter未定义：

opencv高级版本不在含有CvFilter，那么就把类型改成int吧……

3、CvvImage类找不到定义……

高级版本中，以前版本的CvvImage类不见了...为了能够继续使用这个类，下面把这个类的源代码贴出来，使用的时候将该代码加入到工程中便可以使用了。为了方便切换OpenCV的版本，这里用到了一些条件编译宏，来保证代码的灵活性。

      不过OpenCV 2.2.0取消CvvImage这个类，一定是有它的原因的，具体可以在做实验的时候体会这些原因。
