Uncalibrated Photometric Stereo Using Superquadrics with Cast Shadow

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Formulated as an inverse problem of computer graphics, inverse rendering (or photometric stereo) can estimate parameters, such as the shapes and configurations of objects and light sources in the scene, from a set of images. Such results can be useful for applications including recognition, inspection, and/or VR. In the present paper, we extend previous studies in such a way as to incorporate more complex image formation models, specifically superquadrics with cast shadows, that are implemented on a standard graphics API and verify the framework on synthetic and real-world data.
