Hi My input is UMat 32FC1 and I'd like to compute abs() but I get a compile error "no matching function for call to 'abs'". my code works find for Mat, but I'd like to use the GPUs. I also tried convertScaleAbs() but it outputs an 8 bit value. Any ideas on what's the most efficient way to do this other than writing my own ocl kernel? Cheers2u Eddie
