UNSUPERVISED LEARNING FOR TEMPORAL SEARCH SPACE REDUCTION IN THREE-DIMENSIONAL SCENE RECOVERY

Abstract

Methods for three-dimensional scene recovery traverse scene spaces (typically along epipolar lines) to compute two-dimensional image feature correspondences. These methods ignore potentially useful temporal information presented by previously processed frames, which can be used to decrease search space traversal. In this work, we present a general framework which models relationships between image information and recovered scene information specifically for the purpose of improving efficiency of three-dimensional scene recovery. We further present three different methods implementing this framework using either a naive Nearest Neighbour approach or a more sophisticated collection of associated Gaussians. Whilst all three methods provide a decrease in search space traversal, it is the Gaussian-based method which performs best, as the other methods are subject to the (demonstrated) unwanted behaviours of convergence and oscillation.
