Web21 de jul. de 2024 · on Jul 29, 2024 The warpAffine function like all other image transform functions are designed for up to 4 channels. All transform functions have several branches for different platforms (vectorization for x86, ARM, IPP back-end, OpenCV Hall, etc) and different interpolation, border, etc.
warpAffine fails for images with more than 4 channels when …
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.
