I have a image (the colored matrix) that I wanna conform into a given space where each pixel is the position in the original image (the greeninsh-yellowings one) and I put there the result.

The concept seems to work, in fact it works really nice on magnification but pretty poor on downsampling (see the side of the box) making this on opengl / directx is easy since they take care about anisotropic filtering of the texture etc but OpenCV fails on that (please open the image in full size)

Any idea for improve this?

Regards.
