Web16 de jun. de 2024 · Then, I have to extract the patches: I can do it using cv::cuda::warpAffine to leverage the computation to the graphic card and use the data stored inside. I checked the code and it doesn't seems that cv::cuda::warpAffine expect the Ms matrix to be already stored in the GPU but rather a creation and allocation is performed Web8 de mar. de 2014 · affine warp large asked Mar 8 '14 amm 1 I am using getRotationMatrix2D to rotate an image, passing the rotation matrix into warpAffine. On small images (e.g. 4465x1745 or smaller) the output is what I expect. Larger images (e.g. 14882x5815) give weird results. The same image scaled down gives expected results.
