Implementation of PCT signature extractor (position-color-texture) and evaluation of their Signature Quadratic Form Distance (SQFD).

first commit. Interface for sinusoidal pattern profilometry has been added along with stubs functions in the implementation class. The new interface inherits from StructuredLightPattern

Added markers to sinusoidal patterns

computePhaseMap for Fourier transform profilometry

computePhaseMap for Fourier transform profilometry

added phase map computation for PSP. Changed the maskDftRegion to frequencyFiltering. It uses regions of interest and can filter symmetrically. Also added computeShadowMask and computeDataModulationTerm

changed formatting in structured light module. First commit for the phase unwrapping module. So far, pixel reliabilities are computed and edges are sorted in a histogram.

Fixed an error in edges sorting. Added the unwrap histogram method. It computes the number of 2*Pi that has to be added to each pixel to unwrap the phase map

added an example for phase unwrapping and a test that unwraps a simple phase map

Added documentation draft and a small example that can generate sinusoidal patterns

removed unnecessary include

added a few comments in sinusoidalpattern.cpp and histogramphaseunwrapping.cpp. Removed some redudancy about mask in the reliability computation. Changed formatting

projector calibration as a sample

Minor clean up. There was no need to keep these lines.

optflow: fix test failure

MSVS2013:
- DenseOpticalFlow_GlobalPatchColliderDCT.ReferenceAccuracy
- DenseOpticalFlow_GlobalPatchColliderWHT.ReferenceAccuracy

allows trading corner precision for corner quantity

* 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

It is required for proper work of toolchains
