 # GeoPatch Descriptor
 
 This repository contains the original implementation of the descriptor "<b>Learning Geodesic-Aware Local Features from RGB-D Images</b>", published at Computer Vision and Image Understanding journal. GeoPatch is by design invariant to isometric non-rigid deformations of surfaces by leveraging geodesic-invariant sampling, designed as a mapping function before descriptor computation is performed from photometric information.
