This paper introduces a metric that measures symmetry in tree graphs, which allows for a statistical characterization of GP solutions by their architectural "shapes." A ...

Prior work has argued that when a Lambertian surface in fixed pose is observed in multiple images under varying distant illumination, there is an equivalence class of surfaces giv...

We present a new technique for extracting local features from images of architectural scenes, based on detecting and representing local symmetries. These new features are motivate...

In this paper, we formulate symmetry detection for incompletely specified functions as an equation without using cofactor computation and equivalence checking. Based on this equat...

A novel shape descriptor based on the histogram matrix of pixel-level structural features is presented. First, length ratios and angles between the centroid and contour points of ...
