This module contains utilities for calculating local image gradients, discrete joint probability histograms, mutual information scores, and the descriptor extractors of the following features:
- Dense Adaptive Self-Correlation features (DASC, TPAMI2016)
- Local Binary Similarity Patterns (LBSP, CRV2013)
- Local Self Similarity features (LSS, CVPR2007)
- Shape Context features (SC, TPAMI2002)
An implementation of Felzenszwalb’s HOG features with proper optimization under an OpenCV interface should eventually be added to this module.
