Content Based 3D Shape Retrieval A Survey
Large databases of 3-dimensional (3D) data are becoming available on the Internet, and in various domains such as Computer Aided Design (CAD), Molecular Biology (3D Protein Models), Computer Graphics, Medicine and Archeology to name a few. As the number and variety of the 3D models(3D shapes) continue to grow, there has been an increasing interest in applications to help people search in these ...
متن کاملContent Based 3D Shape Retrieval
Recent developments in techniques for modeling, digitizing and visualizing 3D shapes has led to an explosion in the number of available 3D models on the Internet and in domain-specific databases. Currently, large archives recording cultural heritage models like the David of Michelangelo [11], and the Minerva of Arezzo [7] are obtained by laser scanning projects. Also archives containing domain-...
متن کاملShape-based 3d Model Retrieval System Based on Elevation Descriptor
Recently, with the construction of digital libraries, the management of the large multimedia databases becomes an important issue. Unfortunately, traditional keyword searching techniques are not always effective for multimedia information. Thus, computer science has make incredible progress in retrieval of multimedia data based on image content. However, most of retrieval systems are focus on t...
متن کاملA 3D Shape Measurement System
This paper presents a 3D shape measurement system for stationary objects which features reduced cost, high accuracy, and ease of implementation. An integral part of this system is a 2D multi-plane camera calibration technique, implemented with improvements to the automation and corner extraction over traditional techniques. A binary coded structured light plus phase shifting technique is implem...
متن کاملShape-based retrieval of 3D mesh models
This paper addresses the issue of 3D mesh indexation by using shape descriptors (SDs) under constraints of geometric and topological invariance. A new shape descriptor, the Canonical 3D Hough Transform Descriptor (C3DHTD) is here proposed. Intrinsically topologically stable, the C3DHTD is not invariant to geometric transformations. Nevertheless, we show mathematically how the C3DHTD can be opti...
