To transform from cvmat to iplimage use function.
Mat to iplimage conversion opencv.

While in the c interface you used to work with pointers here it s no longer the case.

Intensity val 0 contains a value from 0 to 255.
Do remember that you need to allocate the iplimage structure which is lack.
Cv mat is the new type introduce in opencv2 x while the iplimage is the legacy image structure.
In the c interface we have mostly mat objects.
Thanks for this article.
Although cv mat does support the usage of iplimage in the constructor parameters the default library does not provide function for the other way.
These objects may be freely converted to both iplimage and cvmat with simple assignment.
Hi kt10aan in opencv 3 they removed the cv mat constructor with iplimage i e.
Now for converting the mat object you can use either the iplimage or the cvmat operators.
Note the ordering of x and y.
Cv mat has a conversion operator to iplimage so if you have something that converts the iplimage to a qimage just use that or make the probably minor adjustments to take the cv mat directly the memory layout is the same it s just the header that is different.
Since in opencv images are represented by the same structure as matrices we use the same convention for both cases the 0 based row index or y coordinate goes first and the 0 based column index or x coordinate follows it.
To transform from iplimage to cvmat use function.
You will need to extract the image header information manually.
