Shape description is an important task in content-based image retrieval (CBIR). A variety of
techniques have been reported in the literature that aims to represent objects based on their …

This paper presents a novel approach for both fast and accurately retrieving similar shapes.
A hierarchical string cuts (HSCs) method is proposed to partition a shape into multiple level …

In this paper we consider the distance between the shape centroid computed from the shape
interior points and the shape centroid computed from the shape boundary points. We show …

In this paper we study the ADR shape descriptor ρ (S), where ADR is short for “asymmetries
in the distribution of roughness”. This descriptor was defined in 1998 as the ratio of the …

Shape based feature is a widely used method in Content based Image Retrieval (CBIR) for
similarity measurements because contours of an image provide relevant information for …

This paper presents a 2D shape retrieval system using moment invariants based on a
representation of image boundary of the shape objects. The original binary image is …

The doctoral thesis deals with the study of quantitative aspects of shape attribute ssuitable
for numerical characterization, ie, shape descriptors, as well as the theory of uncertainty …

In this paper, we have introduced a new way to analyze binary shapes using a new Fourier
based descriptor, which is the smoothed derivative of the phase of the Fourier descriptors. It …

Content-based image retrieval (CBIR) is still in its early stages, although several attempts
have been made to solve or minimize challenges associated with it. CBIR techniques use …

In this paper we study a shape descriptor ρ (S) that is defined as the ratio of the squared
distance between centroids and the squared diameter of shape S (ie, a set in the plane) …
