      Vladislav Samsonov authored
      * 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

      Complete DIS optical flow implementation · b96a5f59
      Alexander Bokov authored
      Added variational refinement as a separate class (based on implementation
      inside DeepFlow, but significantly accelerated, about 4-6 times faster),
      accelerated the main dense inverse search algorithm. Added several new
      features including patch mean normalization for increased robustness to
      illumination changes and spatial propagation, which often helps to recover
      from errors introduced by the coarse-to-fine scheme. Expanded the
      documentation, added new accuracy and perf tests. Refactored some of
      the already existing optical flow accuracy tests.

      Partial DIS implementation and OF benchmark · d4c3765e
      Alexander Bokov authored
      Basic interfaces and a partial implementation of the Dense Inverse
      Search (DIS) optical flow algorithm without variational refinement. Also
      added a python benchmarking script that can evaluate different optical
      flow algorithms on the MPI Sintel and Middlebury datasets and build
      overall comparative charts.
