Modeling of 2D Parts Applied to Database Query

Guillaume-Alexandre Bilodeau and Robert Bergevin

Abstract - This paper presents recent developments in a project aimed at the design of an image database query engine, where the images are searched using 3D part-based object models. This is a novelty since most existing image database query engines search images by comparing colors, textures and 2D shape of regions in the images. In our project, 3D part-based models are built from qualitative volumetric primitives. This paper proposes a method to hypothesize such volumetric primitives from projected object parts.It combines concepts from two existing approaches, a model-fitting and a rule-based approach. Using fuzzy logic, this new method can produce multiple hypotheses to attain the robustness necessary for processing 2D parts originating from 2D images of realscenes. A detailed description of the method is presented along with promising preliminary results.
