Dmitry Matveev	85fad1504a	Merge pull request #13030 from dmatveev:tutorial * G-API: First steps with tutorial * G-API Tutorial: First iteration * G-API port of anisotropic image segmentation tutorial; * Currently works via OpenCV only; * Some new kernels have been required. * G-API Tutorial: added chapters on execution code, inspection, and profiling * G-API Tutorial: make Fluid kernel headers public For some reason, these headers were not moved to the public headers subtree during the initial development. Somehow it even worked for the existing workloads. * G-API Tutorial: Fix a couple of issues found during the work * Introduced Phase & Sqrt kernels, OCV & Fluid versions * Extended GKernelPackage to allow kernel removal & policies on include() All the above stuff needs to be tested, tests will be added later * G-API Tutorial: added chapter on running Fluid backend * G-API Tutorial: fix a number of issues in the text * G-API Tutorial - some final updates - Fixed post-merge issues after Sobel kernel renaming; - Simplified G-API code a little bit; - Put a conclusion note in text. * G-API Tutorial - fix build issues in test/perf targets Public headers were refactored but tests suites were not updated in time * G-API Tutorial: Added tests & reference docs on new kernels * Phase * Sqrt * G-API Tutorial: added link to the tutorial from the main module doc * G-API Tutorial: Added tests on new GKernelPackage functionality * G-API Tutorial: Extended InRange tests to cover 32F * G-API Tutorial: Misc fixes * Avoid building examples when gapi module is not there * Added a volatile API disclaimer to G-API root documentation page * G-API Tutorial: Fix perf tests build issue This change came from master where Fluid kernels are still used incorrectly. * G-API Tutorial: Fixed channels support in Sqrt/Phase fluid kernels Extended tests to cover this case * G-API Tutorial: Fix text problems found on team review	6 years ago

Pavel Rojtberg	0d65397ae7	videoio: remove cap_libv4l in favour of cap_v4l cap_libv4l depends on an external library (libv4l) yet is still larger (1966 loc vs 1822 loc). It was initially introduced copy pasting cap_v4l in order to offload various color conversions to libv4l. However nowadays we handle most of the needed color conversions inside OpenCV. Our own implementation is better tested and (probably) also better performing. (as it can optionally leverage IPP/ OpenCL) Currently cap_v4l is better maintained and generally the code is in better shape. There is however an API difference in getting unconverted frames: * on cap_libv4l one need to set `CV_CAP_MODE_GRAY=1` or `CV_CAP_MODE_YUYV=1` * on cap_v4l one needs to set `CV_CAP_PROP_CONVERT_RGB=0` the latter is more flexible though as it also allows accessing undecoded JPEG images. fixes #4563	6 years ago
