Get start with OpenCV

            花了三天的时间才把OpenCV装好~这个过程简直艰辛。。。昨天晚上我都差点要绝望了，心里难受啊~最后不知道尝试了多少次之后，libgtk2.0-dev终于装上去了.

          apt-get 之前一直找不到libgtk2.0-dev 这个包，无比纠结，时间都砸进去了。仅仅只是搭建开发环境而已，却花了这么多时间，心疼啊~我仅剩不多的暑假时光~如果有viewer和我遇到同样的问题，那我建议——重装一次你的Ubuntu吧~

编译遇到点小麻烦，不过搞定也花什么时间。

Get start with OpenCV, the first demo.

code purpose:
	This demo is coded for someone who is the first time 
to code with OpenCV (A very powerful computer vision library.)
Something like your "Hello world" is here.

************************************************************/

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/highgui/highgui_c.h"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/imgproc/imgproc_c.h"

int main(int argc,char* argv[])
{
	IplImage* img = cvLoadImage(argv[1],CV_LOAD_IMAGE_COLOR);
	//IplImage is a structure which could store a image that retured by function 'cvLoadImage'

	cvNamedWindow("Example1",CV_WINDOW_AUTOSIZE);
	//cvNamedWindow is a function which would help you to creat a window.

	cvShowImage("Example1",img);
	//Obviously, show the picture that you inputed.

	cvWaitKey(0);
	//pause and let the user see the picture.

	cvReleaseImage(&img);
	//Finally, release the struture, otherwise, memory leak !

	return 0;
}

没完，编译的参数看的库自带的demo的脚本，不难。这里给出能用的简单的脚本，在当前工作目录下运行即可

#!/bin/sh

for i in *.c; do
    echo "compiling $i"
    gcc -ggdb `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`;
done
