The proposed shape descriptor is based on the beams originated from a boundary point,
which are defined as lines connecting that point with the rest of the points on the boundary …

This paper presents a novel approach to identify complex shapes based on the Radon
transform. We propose an adaptation of Radon transform called R-transform, which is …

A new algorithm for detecting dominant points and polygonal approximation of digitized
closed curves is presented. It uses an optimal criterion for determining the region-of-support …

We describe a new algorithm that detects a set of feature points on the boundary of an 8-
connected shape that constitute the vertices of a polygonal approximation of the shape itself …

This paper presents a new algorithm that detects a set of dominant points on the boundary of
an eight-connected shape to obtain a polygonal approximation of the shape itself. The set of …

We propose a lossless compression method based on a chain code composed of only three
symbols. The method is applicable to compress 2-D binary object shapes, and it consists of …

This paper proposes a novel feature-based invariant descriptor termed Radon composite
features (RCFs) for planar shapes. Instead of analyzing shapes directly in the spatial …

In this paper, we present a pattern recognition method that uses dynamic programming for
the alignment of Radon features. The key characteristic of the method is to use dynamic time …

A new method for dominant point detection is presented. This method can be classified as
search corner detection using some significant measurement other than curvature category …

The chapter focuses on one of the key issues in document image processing ie, graphical
symbol recognition. Graphical symbol recognition is a sub-field of a larger research domain …
