Pierre Chatelier	00e8c7810f	LineIterator witout a Mat (#13843 ) * LineIterator witout a Mat cv::LineIterator can be used without being attached to any cv::Mat, it only needs the size and type of data. An alternative constructor has been defined for that. In that case, a LineIterator can no more be dereferenced with the * operator, but pos() still returns valid pixel positions. It can be useful when LineIterator is just used to compute positions of pixels on a line, without requiring to build a Mat just for that. Use case : with a dataset that would represent a huge image, pixel positions can be pre-computed before querying the dataset API. * Update imgproc.hpp removed trailing spaces * Update drawing.cpp fixed warning	6 years ago

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
