图像格式处理,c++,cv::MAt,IplImage

 

1、cv::mat

string src_im_pth;
im_src = cv::imread(src_im_pth, -1);
if (im_src.empty()) {
fprintf(stderr, "---[wjj] Error! image %s not valid
", src_im_pth.c_str());
}
else {
//deal test_img, to ASVLOFFSCREEN
ASVLOFFSCREEN ImgDataInput;
ImgDataInput.i32Height = im_src.rows;
ImgDataInput.i32Width = im_src.cols;
ImgDataInput.u32PixelArrayFormat = ASVL_PAF_RGB24_B8G8R8;
ImgDataInput.ppu8Plane[0] = im_src.data;
ImgDataInput.ppu8Plane[1] = im_src.data + 1;
ImgDataInput.ppu8Plane[2] = im_src.data + 2;
ImgDataInput.pi32Pitch[0] = ImgDataInput.pi32Pitch[1] = ImgDataInput.pi32Pitch[2] = im_src.step;

}

2、IplImage

string src_im_pth;

IplImage* tmp_src = cvLoadImage(src_im_pth.c_str());//deal test_img, to ASVLOFFSCREEN
ASVLOFFSCREEN GlassSceneInput;
GlassSceneInput.i32Height = tmp_src->height;
GlassSceneInput.i32Width = tmp_src->width;
GlassSceneInput.u32PixelArrayFormat = ASVL_PAF_RGB24_B8G8R8;
GlassSceneInput.ppu8Plane[0] = (MUInt8*)tmp_src->imageData;
GlassSceneInput.pi32Pitch[0] = tmp_src->widthStep;
cvReleaseImage(&tmp_src);

3、IpIImage转Mat

im_src = cvarrToMat(tmp_src);

 4、Mat转IpIImage

			cv::Mat src_mat = cv::imread(im_pth);
			double nWid = src_mat.cols;
			double nHei = src_mat.rows;
			IplImage* tmp_src = cvCreateImage(cvSize(nWid, nHei), IPL_DEPTH_8U, 3);
			*tmp_src = IplImage(src_mat);

5、ASVLOFFSCREEN 转IpIImage再转Mat

        cv::Mat mask;
	ASVLOFFSCREEN *maskData;
	IplImage * PLimg_mask = cvCreateImage(cvSize(frame.cols, frame.rows), IPL_DEPTH_8U, 1);
	MMemCpy(PLimg_mask->imageData, maskData->ppu8Plane[0], maskData->pi32Pitch[0] * maskData->i32Height);
	mask = cv::cvarrToMat(PLimg_mask);
