An eigenvalue decomposition based full polarimetric SAR framework for leaf area index retrieval using entropy-anisotropy features

Present study proposes a novel Full Polarimetric Radar Vegetation Index (FPRVI) for accurate Leaf Area Index (LAI) retrieval using RISAT-1A full-polarimetric SAR data. The eigenvalue-based polarimetric decomposition parameters entropy (H) and anisotropy (A) have been employed to...

Proximal point method with Bregman distance for nonconvex quasi-equilibrium problems

We introduce a Bregman proximal point method for solving pseudomonotone quasi-equilibrium problems. The algorithm is formulated using Bregman distances generated by Legendre functions and allows the bifunction to be nonconvex. Unlike existing Euclidean proximal approaches, our me...
