A Class of Photometric Invariants: Separating Material from Shape and Illumination

14 years 7 months ago

We derive a new class of photometric invariants that can be used for a variety of vision tasks including lighting invariant material segmentation, change detection and tracking, a...

New Area Matrix-Based Affine-Invariant Shape Features and Similarity Metrics

13 years 11 months ago

Download www.cecs.uci.edu

A near-planar object seen from different viewpoints results in differently deformed images. Under some assumptions, viewpoint changes can be modeled by afﬁne transformations. Sh...

Resolution Invariant Surfaces for Panoramic Vision Systems

14 years 7 months ago

Download users.rsise.anu.edu.au

A family of axially symmetric mirror shapes are proposed for panoramic imaging. These shapes keep the resolution in the image invariant to changes in elevation in the scene. In ot...

Affine-invariant diffusion geometry for the analysis of deformable 3D shapes

13 years 5 days ago

Download www.cs.technion.ac.il

We introduce an (equi-)affine invariant diffusion geometry by which surfaces that go through squeeze and shear transformations can still be properly analyzed. The definition of an...
