Helper function for cv::invertAffineTransform() #249

Closed sbudenkov closed 1 year ago

sbudenkov commented 1 year ago

Hi, I can't find something like void cv::invertAffineTransform( InputArray M, OutputArray iM ) from OpenCV. It is also possible with cv::WARP_INVERSE_MAP in cv::warpAffine(). Could you please help me with that. I need it for SimdWarpAffineInit().

I see but what about invert? I need inverted matrix. I can do it using OpenCV but want to do it using Simd.

I added Simd::InvertAffineTransform().

Please close the issue then.
