摘要形状匹配及分类是计算机视觉中的重要问题. 近年来, 以形状上下文为代表的基于轮廓的
形状匹配方法和以奇点图为代表的基于骨架的形状匹配方法获得了长足的发展 …

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 …

There are two categories of partial shape matching problem: whole-to-part matching and
part-to-part matching. The first establishes the best match between an open curve and a part …

We present an approach to identify the plant species from the contour information from
occluded leaf image using a database of full plant leaves. Although contour based 2D shape …

We propose a method for object category localization by partially matching edge contours to
a single shape prototype of the category. Previous work in this area either relies on …

This paper introduces a novel efficient partial shape matching method named IS-Match. We
use sampled points from the silhouette as a shape representation. The sampled points can …

We investigate two problems in elastic curve shape analysis, working within the context of
the square root velocity (SRV) framework. The first of these is to develop specialized …

In the past, the huge and profitable interaction between Pattern Recognition and
biology/bioinformatics was mainly unidirectional, namely targeted at applying PR tools and …

A widely adopted security mechanism is the specification of access control policies by
means of the XACML language. In this paper, we propose a framework, called X-CREATE …

We prove that when a line is approximated using digital line, the error in the slope of the
digital line has a definite upper bound and is strongly dependent on the two pixels chosen …
