Multiple-Kernel Local-Patch Descriptor

25 Jul 2017 Arun Mukundan Giorgos Tolias Ondrej Chum

We propose a multiple-kernel local-patch descriptor based on efficient match kernels of patch gradients. It combines two parametrizations of gradient position and direction, each parametrization provides robustness to a different type of patch miss-registration: polar parametrization for noise in the patch dominant orientation detection, Cartesian for imprecise location of the feature point...
