DescriptorType Fields

BGM is the base descriptor where each binary dimension is computed as the output of a single weak learner.

BGM_BILINEAR refers to same BGM but use different type of gradient binning. In the BGM_BILINEAR that use ASSIGN_BILINEAR binning type the gradient is assigned to the two neighbouring bins.

BGM_HARD 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.

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.

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.

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.

LBGM (alias FP-Boost) is the floating point extension where each dimension is computed as a linear combination of the weak learner responses.
