    /**
     * 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.
