Vadim Pisarevsky 3c7f7de477 avoid possible problems with zero values in tone mapping algorithms (http://code.opencv.org/issues/4020)
10 years ago
Vadim Pisarevsky b37aaa8303 significantly improved parallel non-local means by using granularity parameter in parallel_for_ loop. Because the algorithm deals with sliding sums, it's essential that each thread has enough work to do, otherwise the algorithm gets higher theoretical complexity and thus there is no speedup comparing to 1-thread code (at best).
