// C++: class BoostDesc
/**
* Class implementing BoostDesc (Learning Image Descriptors with Boosting), described in
* CITE: Trzcinski13a and CITE: Trzcinski13b.
*
* desc type of descriptor to use, BoostDesc::BINBOOST_256 is default (256 bit long dimension)
* Available types are: BoostDesc::BGM, BoostDesc::BGM_HARD, BoostDesc::BGM_BILINEAR, BoostDesc::LBGM,
* BoostDesc::BINBOOST_64, BoostDesc::BINBOOST_128, BoostDesc::BINBOOST_256
* use_orientation sample patterns using keypoints orientation, enabled by default
* scale_factor adjust the sampling window of detected keypoints
* 6.25f is default and fits for KAZE, SURF detected keypoints window ratio
* 6.75f should be the scale for SIFT detected keypoints window ratio
* 5.00f should be the scale for AKAZE, MSD, AGAST, FAST, BRISK keypoints window ratio
* 0.75f should be the scale for ORB keypoints ratio
* 1.50f was the default in original implementation
*
* <b>Note:</b> BGM is the base descriptor where each binary dimension is computed as the output of a single weak learner.
* BGM_HARD and BGM_BILINEAR refers to same BGM but use different type of gradient binning. In the BGM_HARD that
* use ASSIGN_HARD binning type the gradient is assigned to the nearest orientation bin. In the BGM_BILINEAR that use
* ASSIGN_BILINEAR binning type the gradient is assigned to the two neighbouring bins. In the BGM and all other modes that use
* ASSIGN_SOFT binning type the gradient is assigned to 8 nearest bins according to the cosine value between the gradient
* angle and the bin center. LBGM (alias FP-Boost) is the floating point extension where each dimension is computed
* as a linear combination of the weak learner responses. BINBOOST and subvariants are the binary extensions of LBGM
* where each bit is computed as a thresholded linear combination of a set of weak learners.
* BoostDesc header files (boostdesc_*.i) was exported from original binaries with export-boostdesc.py script from
* samples subfolder.
