| 2012-10-10 10:09:40 -0600 | asked a question | Rotation of an image with this algorithm I have to do a rotation of an image with this algorithm: we need to define the amount of rotation in terms of an angle. We denote this angle θ meaning that each pixel in f (x, y) is rotated θ degrees. The transformation is defined as
I tried to go through some of the core functionality tutorials, but I'm already lost at the 3rd chapter. I don't know how to do this with c++ and opencv, and I really hope that someone in here can help me. I don't even know how to access one pixel in the matrix and tell it to do - well just something.. |
