Joint Geometry/Texture Progressive Coding of 3D Models

چکیده
Files of 3D models are often large and time-consuming to download. Most 3D viewers need the entire file to display a 3D model even when the user is interested only in a part of or a low-resolution version of the model. Therefore, progressive coding of 3D models is desired. However, existing work studies either the progressive coding of the geometry only, or progressive coding of the texture only. In this paper, we propose a joint geometry/texture coding technique for 3D objects. Both of the geometry and the texture are progressively coded and transmitted to the viewer. The most perceptually important bits are sent before the less important bits, allowing the users to stop the download at any time and yet retain the best quality available at that time.

Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملInvestigating the Effect of Joint Geometry of the Gas Tungsten Arc Welding Process on the Residual Stress and Distortion using the Finite Element Method
Although a few models have been proposed for 3D simulation of different welding processes, 2D models are still more effective in design goals, thus more popular due to the short-time analysis. In this research, replacing "time" by the "third dimension of place", the gas tungsten arc welding process was simulated by the finite element method in two dimensions and in a short time with acceptable ...

متن کاملSensitivity of image-based and texture-based multi-view coding to model accuracy
Multi-view image coding benefits from knowledge of the depicted scene’s 3-D geometry. To exploit geometry information for compression, two different approaches can be distinguished. In texture-based coding, images are converted to texture maps prior to compression. In image-based predictive coding, geometry is used for disparity compensation and occlusion detection between images. Coding perfor...

Automatic texture mapping is an important task in enrichment of the common 3D city models. A significant part of all algorithms for automated texture mapping is the visibility checking. Nowadays most algorithms for texture extraction use visibility check based on z-buffer or polygon intersection in the image plane. Thus, the visibility of particular face is calculated for every frame independen...
