Title: Information Pursuit: A Bayesian Framework for Sequential Scene Parsing,
Abstract: Despite enormous progress in object detection and classification, the problem
of incorporating expected contextual relationships among object instances into
modern recognition systems remains a key challenge. In this work we propose
Information Pursuit, a Bayesian framework for scene parsing that combines prior
models for the geometry of the scene and the spatial arrangement of objects
instances with a data model for the output of high-level image classifiers
trained to answer specific questions about the scene. In the proposed
framework, the scene interpretation is progressively refined as evidence
accumulates from the answers to a sequence of questions. At each step, we
choose the question to maximize the mutual information between the new answer
and the full interpretation given the current evidence obtained from previous
inquiries. We also propose a method for learning the parameters of the model
from synthesized, annotated scenes obtained by top-down sampling from an
easy-to-learn generative scene model. Finally, we introduce a database of
annotated indoor scenes of dining room tables, which we use to evaluate the
proposed approach.
