resample adjoined
first implementation of blur, some are TODO still open
mirror boundary conditions impemented
bilinear value added, now it uses global memory not texture, should work but slow
forward warping
Merge branch 'superres' of https://github.com/arashb/GPULabProj into marco
added additional parameters to be more flexible at runtime: -sp show preprocessed img, -lf load flow
pitches should be correct
switched parameter in backwardRegVal
pitch modified in forward warping, now I get completely black images
renamed u_g to result_g in order not to confuse it with flow->u_g
