图像平移

原理自己找书查看；

代码如下：

void Ctry::OnTryTyr1()
{
	 //TODO:  在此添加命令处理程序代码
	IplImage *img = cvLoadImage("C:\\Users\\Administrator\\Desktop\\3838.jpg");
	

	IplImage *move = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 3);

	IplImage* r = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage* g = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage* b = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);

	IplImage* r1 = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage* g1 = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage* b1 = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);

	cvSplit(img, r, g, b, NULL);

	int nHeight = img->height;
	int nWidth = img->width;

	int x = 50;     //水平右移距离
	int y = 50;     //垂直下移距离
	if (x > img->width || y > img->height)
	{
		MessageBox(NULL, "超过图片大小", "错误", MB_OK | MB_ICONERROR);
		return;
	}

	double  temp1=0, temp2=0, temp3=0;
	for (int j = 0; j < r->height; j++)
	{
		for (int i = 0; i < r->width; i++)
		{
			if (i - x>0 && i - x < nWidth && j - y>0 && j - y <nHeight)
			{
				temp1 = cvGetReal2D(r, j - y, i - x);	
				temp2 = cvGet2D(g, j - y, i - x).val[0];
				temp3 = cvGet2D(b, j - y, i - x).val[0];
				cvSetReal2D(r1, j, i, temp1);
				cvSetReal2D(g1, j, i, temp2);
				cvSetReal2D(b1, j, i, temp3);

				}
			else
			{
				cvSetReal2D(r1, j, i, 255);
				cvSet2D(g1, j, i, 255);
				cvSet2D(b1, j, i, 255);
			}
		}
	}
	cvMerge(r1, g1, b1, 0, move);
	cvNamedWindow("move", CV_WINDOW_AUTOSIZE);
	cvShowImage("move", move);
	cvSaveImage("C:\\Users\\Administrator\\Desktop\\move.jpg", move);


	cvNamedWindow("img", CV_WINDOW_AUTOSIZE);
	cvShowImage("img", img);
	cvWaitKey(0);

	cvReleaseImage(&img);
	cvReleaseImage(&r);
	cvReleaseImage(&g);
	cvReleaseImage(&b);
	cvReleaseImage(&r1);
	cvReleaseImage(&g1);
	cvReleaseImage(&b1);
	cvReleaseImage(&move);
	cvDestroyWindow("move");
	cvDestroyWindow("r1");
	cvDestroyWindow("img");
}
