Progressive Coding of 3-D Graphic Models
Based on state-of-the-art graphic-simplification techniques and progressive image-coding schemes, we propose a new hierarchical three-dimensional graphic-compression scheme in this research. This scheme progressively compresses an arbitrary polygonal mesh into a single bitstream. Along the encoding process, every output bit contributes to the reduction of coding distortion, and the contribution...
متن کاملEmbedded Coding of 3 D Graphic
A noval progressive compression method which encodes a 3D graphic models into an embedded bit stream is investigated in this research. The coder rst encodes the coarsest resolution of the model, and then includes the information of ner details gradually. A rate-distortion model is used in the integration of diierent types of bit streams into a single embedded bit stream to optimize the overall ...
متن کامل3D Computer Graphic Compression
Nowadays, 3D graphical models have become commonplace in most computer graphics related industries. The accuracy and realism of these 3D graphics are achieved by fine geometric details which present challenges in rendering performance; transmission bandwidth; and storage capacities. All these motivate a need for compressing geometric data. In this paper, I talk about two compression techniques ...
متن کاملOverview of 3-D Reconstruction from Images
This article summarizes recent advancements of the theories and techniques for 3-D reconstruction from multiple images. We start with the description of the camera imaging geometry as perspective projection in terms of homogeneous coordinates and the definition of the intrinsic and extrinsic parameters of the camera. Next, we described the epipolar geometry for two, three, and four cameras, int...
متن کاملSpatial Compounding of 3-D Ultrasound Images
One of the most promising applications of 3-D ultrasound lies in the visualisation and volume estimation of internal 3-D structures. Unfortunately, the quality of the ultrasound data can be severely degraded by artifacts, especially speckle, making automatic analysis of the 3-D data sets very di cult. In this paper we investigate the use of 3-D spatial compounding to reduce speckle. We develop ...
