/**

|
* \file DisparityStereoSGBM.h
|
|
* \brief Measure the disparity between two images using the SGBM method (OpenCV)
|
|
* The class implements the modified H. Hirschmuller algorithm
|
|
* that differs from the original one as follows:
|
|
* - By default, the algorithm is single-pass, which means that you consider only 5 directions
|
|
* instead of 8. Set mode=StereoSGBM::MODE_HH in createStereoSGBM to run the full variant of the
|
|
* algorithm but beware that it may consume a lot of memory.
|
|
* - The algorithm matches blocks, not individual pixels. Though, setting blockSize=1 reduces the
|
|
* blocks to single pixels.
|
|
* - Mutual information cost function is not implemented. Instead, a simpler Birchfield-Tomasi
|
|
* sub-pixel metric from @cite BT98 is used. Though, the color images are supported as well.
|
|
* - Some pre- and post- processing steps from K. Konolige algorithm StereoBM are included, for
|
|
* example: pre-filtering (StereoBM::PREFILTER_XSOBEL type) and post-filtering (uniqueness
|
|
* check, quadratic interpolation and speckle filtering).
