Shape Google: a computer vision approach to isometry invariant shape retrieval
Maks Ovsjanikov, Alexander M. Bronstein, Michael M. Bronstein, Leonidas Guibas · 2009
Feature-based methods have recently gained popularity in computer vision and pattern recognition communities, in applications such as object recognition and image retrieval. In this paper, we explore analogous approaches in the 3D world applied to the problem of non-rigid shape search and retrieval in large databases.
