RAID: A Relation-Augmented Image Descriptor

This relation-augmented image descriptor supports queries based on relations between image regions, like a person riding object X, or a plank bridging two objects. RAID successfully extracts non-trivial images, demonstrating complex inter-region relations that are easily missed or erroneously classified by existing methods.

Learning How Objects Function via Co-Analysis of Interactions

Introducing a co-analysis method that learns a functionality model for an object category, (for example, strollers or backpacks). The co-analysis localizes the studied properties to the specific locations, or surface patches, that support specific functionalities of the shapes, enabling functionality-aware modeling applications.
