This handbook provides an up-to-date compendium of fundamental computer science
topics, techniques, and applications. Along with updating and revising many of the existing …

We describe a new hierarchical representation for two-dimensional objects that captures
shape information at multiple levels of resolution. This representation is based on a …

We present a novel approach to finding a correspondence (alignment) between two curves.
The correspondence is based on a notion of an alignment curve which treats both curves …

In this paper, we discuss the criteria that should be satisfied by a descriptor for nonrigid
shapes with a single closed contour. We then propose a shape representation method that …

We propose an approach for matching distorted and possibly occluded shapes using
dynamic programming (DP). We distinguish among various cases of matching such as …

Computers accept human user input in various ways. One of the most common input devices
is the keyboard. Addi tional types of input mechanisms include mice and other pointing …

Curve matching is one instance of the fundamental correspondence problem. Our flexible
algorithm is designed to match curves under substantial deformations and arbitrary large …

In this paper, we are going to present a novel shape similarity retrieval algorithm that can be
used to match and recognize 2D objects. The match process uses a new multi-resolution …

Cell nuclei detection is a challenging research topic because of limitations in cellular image
quality and diversity of nuclear morphology, ie, varying nuclei shapes, sizes, and overlaps …

We propose a simple approach to evolution of polygonal curves that is specially designed to
fit discrete nature of curves in digi-tal images. It leads to simplification of shape complexity …
