Before: we check every pixel of image by score (FH * FW loop operations)
After: select which pixels are interesting for us and after that make all operations in loop (~70 loop operations)

Final speedup on test image (only detect function):
246ms -> 79ms

Changes resulted in ~5-10x speedup on a gtx970, no apparent loss in accuracy or other negative effects noticed.
