Conversion from IplImage* to cv::MAT

Question

I searched to convert an IplImage* to Mat, but all answers were about the conversion to cvMat.

How, can I do it? and what is the difference between Mat and cvMat?

Answer 1

• cv::Mat or Mat, both are same.

• Mat has a operator CvMat() so simple assignment works

Convert Mat to CvMat

Mat mat = ---------;
CvMat cvmat = mat;

Convert CVMat to Mat

Mat dst = Mat(cvmat, true);  

Convert Mat to IplImage*

> For Single Channel

IplImage* image = cvCloneImage(&(IplImage)mat); 

> For Three Channel

IplImage* image = cvCreateImage(cvSize(mat.cols, mat.rows), 8, 3);
IplImage ipltemp = mat;
cvCopy(&ipltemp, image);

Hope this helps you. Cheers :)
