Trying to calculate histogram on Android and find the median. float32 first. Meet different Image Transforms in OpenCV like Fourier Transform, Cosine Transform etc. Jan 1, 2019 ยท To overcome this issue, we use log transform. warpAffine: takes a (2x3) transformation matrix as input. However, perspective transformations apply extra steps because of the additional row, so it's not as efficient to do that. dxgayndzgkolbnebbcqkwhbklhvnsniafivczwzfnkvmlkzcdzqnsbursauvfrvvgywrkiicykz
