The advances in 3D data acquisition techniques, graphics hardware, and 3D data modeling
and visualizing techniques have led to the proliferation of 3D models. This has made the …

This paper introduces the importance of 3D shape retrieval frameworks in 3D smart cities,
and proposes a unified framework for 3D shape retrieval. The proposed method is based on …

Since object similarity is a subjective matter, the gap between low-level feature
representations and high-level semantic concepts is a major problem in the field of content …

In this paper, we will propose a new exterior shape feature, ART-based elevation descriptor
(ART-ED), and a new interior shape feature, shell grid descriptor (SGD), for 3D model …

In recent decades, Computer aided retrieval, analysis of text, image data and graphical data
technology are developing rapidly. However, the development in the field of 3D model …

Nowadays many three dimensional models feature color information together with the shape
description. However current content-based retrieval schemes for 3D models are based on …

3D shape retrieval is a problem of current interest in different fields, especially in the
mechanical engineering domain. According to our knowledge, multifeature based …

Suppose that we want to compare k different systems, where/spl mu//sub i/denotes the
steady state mean performance of system i. Our goal is to use simulation to pick the" best" …

The demand for a content-based 3D model retrieval system becomes urgent. Hence, we
propose a novel feature, called principal plane descriptor (PPD), for 3D model retrieval. The …

In this paper, a 3D model retrieval approach based on the combination of different PCA
plane projection approaches will be proposed. First, each 3D model is aligned by the …
