Zhigang Gong	2e49ca4903	Avoid unmap an umat(ocl) which hasn't been mapped at all. According to opencl 1.2 spec 5.4.2: enqueues a command to unmap a previously mapped region of a memory object. ... CL_INVALID_VALUE if mapped_ptr is not a valid pointer returned by clEnqueueMapBuffer, or clEnqueueMapImage for memobj. So if the u->data is not from a clEnqueueMapBuffer call, we should not call clEnqueueUnmapMemObject() unmap it. With this patch, the cases ./opencv_test_video --gtest_filter=OCL_Video/FarnebackOpticalFlow.Mat/* could work well with beignet 0.9.1, Otherwise, it will get a CL_INVALID_VALUE at the clEnqueueUnmapMemObject().

Benjamin Flesch	62533d0d26	perspectiveTransform simplify assert() for better debuggin When using perspectiveTransform in rather complicated settings, it would be easier for developers to have two separate assertions for each part of the boolean expression in order to pinpoint problems more efficiently. In my case I am struggling in Python2.7 with finding out whether scn+1 == m.cols or the depth == CV_32F \|\| depth == CV_64F is making a problem, which is kind of hard.	11 years ago
