Namgoo Lee	fb8e652c3f	Add CV_16UC1 support for cuda::CLAHE Due to size limit of shared memory, histogram is built on the global memory for CV_16UC1 case. The amount of memory needed for building histogram is: 65536 * 4byte = 256KB and shared memory limit is 48KB typically. Added test cases for CV_16UC1 and various clip limits. Added perf tests for CV_16UC1 on both CPU and CUDA code. There was also a bug in CV_8UC1 case when redistributing "residual" clipped pixels. Adding the test case where clip limit is 5.0 exposes this bug.	6 years ago
