Hello. Thanks for your answers. I've found my mistakes. In fact, I was just forgetting the position of the center of rotation. I was (stupidly) thinking it was in the center of the image in the algorithm I gave you. But it was not the case. Taking the center of rotation at the bottom left gave...

I assume that the values are correct. They are given by : http://spiff.rit.edu/match/match-0.16/match.html

Hello, thanks for trying to help me. This is a linear transformation between coordinates (x, y) and (x', y'): x' = A + Bx + Cy y' = D + Ex + Fy a, d: describe the translation between the two systems b,c,d,e: describe rotation and magnification magnification = sqrt(b*b + c*c); rotation angle =...

Hello everybody, Sorry to ask you something that may be easy for you but I'm stuck. For example I have 2 images (size 2056x2056). One image of reference and the other is the same rotated from -90degrees. Using a program with keypoints, it gives me a transform matrix : a=2.056884522e+03...
