Evidence Accumulation for Spatial Reasoning in Aerial Image Understanding

摘要

This document describes a control structure for building an Image Understanding System. This system can deal with objects with diverse appearances when consistent spatial relations exist between objects. By accumulating consistent predictions originated from existing instances, our system can dynamically reason about what to do in order to construct interpretations of the image. This paper, discusses parts of the proposed system - the representation of spatial knowledge, the accumulation of evidence, the focus of attention mechanism, and the integration of constraints for top-down control.
