Shape Retrieval Using Hierarchical Total Bregman Soft Clustering
Shape Retrieval Using Hierarchical Total Bregman Soft Clustering
In this paper, we consider the family of total Bregman divergences (tBDs) as an efficient and robust "distance" measure to quantify the dissimilarity between shapes. We use the tBD-based l <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -norm center as the representative of a set of shapes, and call it the t-center. First, we …
