optflow: RLOF fixes (python-binding, status flag, flat textures) (#2097) * * Bugfix for python-binding related to issue #2094. Copying the prevPtsMat to prevPoints was broken, when using python-binding. * * Connect the blurred image correctly to CROSS support region segmentation. This allows to compute more robust support region shapes. Commit refers to issue #2094. * * Bugfix to avoid the unintended assertion on flat textures discussed in issue #2094. * * Bugfix on SparseRLOFOpticalFlow status was wrongly to to 0 if forward backward error < threshold, which is wrong. Inequation has been corrected. Refers to in issue #2087. * small documentation changes * bugfix on assertions and small test changes

Add robust local optical flow (RLOF) implementations (#1940) * Add robust local optical flow (RLOF) implementations which is an improved pyramidal iterative Lucas-Kanade approach. This implementations contains interfaces for sparse optical flow for feature tracking and dense optical flow based on sparse-to-dense interpolation schemes. Add performance and accuracy tests have been implementation as well as documentation with the related publications * - exchange tabs with spaces - fix optflow.bib indentation - remove optflow_o.hpp - change RLOFOpticalFlowParameter interfaces to Ptr<RLOFOpticalFlowParameter> to remove error on building. Fix warnings * introducing precompiler flag RLOD_SSE * remove header that could not be found * remove whitespaces fix perf and accuracy tests * remove x86intrin.h header * fix ios and arm by removing last sse commands * fix warnings for windows compilation * fix documentation RLOFOpticalFlowParameter * integrate cast to remove last warnings * * add create method and function inferfaces to RLOFOpticalFlowParamter to enable python wrapper interfaces * white space fixes / coding style * fix perf test * other changes: precomp.hpp / static * use Matx44f and Vec4f instead of Mat * normSigmas into constants * replace ceil() calls * maximum level is set to 5 so that it is similar value used in the papers * implement paralellized horizontal cross segmentation as used in Geistert2016 * drop dead code * Avoid using "data" and "step" calculations. Use .ptr<mat_type>(row, col) instead. * Avoid using "data" and "step" calculations. Use .ptr<mat_type>(row, col) instead. * bugfix on BEPLK with ica and adapt the accuracy tests * more 'static' functions * bugfix after changing ptr + step to .ptr(y,x) calls by adjusting ROI of prevImage, currImage and derivI as well as changing the offset of the points in the invoker classes. * add some static_cast to avoid warning * remove 50 grid size sample from perf test. This grid size is to sparse for the epic interpolation * remove notSameColor function since it is not used anymore

The while loop in member function buildPyramid in deepflow.cpp terminated as a result of the break statement and never as a result of the termination criteria because the "i" variable in the while loop was never incremented. Changed the while loop into a for loop Changed the while loop into a for loop in the member function buildPyramid in deepFlow.cpp removed trailing whitespace

This patch adds ocl kernels to accelerate Dense Inverse Search based optical flow algorithm, it acclerates 3 parts in the algorithm, including 1) Structure tensor elements compute, 2) Patch inverse search, 3) Densification compute. Perf and accuracy test are also added. The perf test shows it is 30% faster than the current implementation. Signed-off-by: Li Peng <peng.li@intel.com>

* Minor fixes * Start adding correspondence finding * Added finding of correspondences using GPC * New evaluation tool for GPC * Changed default parameters * Display ground truth in the evaluation tool * Added training tool for MPI Sintel dataset * Added the training tool for Middlebury dataset * Added some OpenCL optimization * Added explanatory notes * Minor improvements: time measurements + little ocl optimization * Added demos * Fixed warnings * Make parameter struct assignable * Fix warning * Proper command line argument usage * Prettified training tool, added parameters * Fixed VS warning * Fixed VS warning * Using of compressed forest.yml.gz files by default to save space * Added OpenCL flag to the evaluation tool * Updated documentation * Major speed and memory improvements: 1) Added new (optional) type of patch descriptors which are much faster. Retraining with option --descriptor-type=1 is required. 2) Got rid of hash table for descriptors, less memory usage. * Fixed various floating point errors related to precision. SIMD for dot product, forest traversing is a little bit faster now. * Tolerant floating point comparison * Triplets * Added comment * Choosing negative sample among nearest neighbors * Fix warning * Usage of parallel_for_() in critical places. Performance improvments. * Simulated annealing heuristic * Moved OpenCL kernel to separate file * Moved implementation to source file * Added basic accuracy tests for GPC and PCAFlow * Fixing warnings * Test accuracy constraints were too strict * Test accuracy constraints were too strict * Make tests more lightweight
