Hierarchical 2D Mesh Design and Compression for Video

چکیده
This paper introduces two-dimensional (2D) hierarchical, content-based mesh modeling and compression for interactive digital video processing. The hierarchical nature of the mesh model enables diierent users to employ diierent meshes of varying level of detail to represent the same content depending on the computational resources and channel bandwidth that are available. In particular , a new mesh decimation procedure is proposed to design hierarchical content-adaptive 2D meshes such that each mesh layer (representing a diierent level of spatial hierarchy) is a subset of the previous higher detail mesh and has Delaunay topol-ogy. A method for hierarchical compression of such meshes is also discussed. Experimental results are presented on self-transsguration using 2D hierarchical content-based Delaunay meshes.

Hierarchical 2-D mesh representation, tracking, and compression for object-based video
This paper proposes methods for designing, tracking and coding hierarchical 2D content-based mesh representations. The design procedure consists of constructing a ne-to-coarse hierarchy of Delaunay meshes, using image-and shape-based criteria for mesh geometry simpliication. Hierarchical tracking employs a coarse-tone strategy with mesh-based motion vector optimization. We introduce new techniq...
متن کاملOptimal 2-D hierarchical content-based mesh design and update for object-based video
-Representation of video objects using hierarchical 2D content-based meshes for accurate tracking and level of detail (LOD) rendering have been previously proposed, where a simple suboptimal hierarchical mesh design algorithm was employed. However, it was concluded that the performance of the tracking and rendering very much depends on how well each level of the hierarchical mesh structure fits...
متن کاملMPEG-4 Low Bit Rate Video Coding Using 2D Mesh
In this paper, we propose an implementation method, for video coding at low bit rates, which combines MPEG-4 2D meshes and H.263 video encoding. Methods for objectbased compression and composition of natural and synthetic video content are emerging in standards like MPEG-4. In this work, we only concern about the implementation of 2D uniform meshes for coding of natural scenes. In order to achi...
متن کامل3D Model compression using Connectivity-Guided Adaptive Wavelet Transform built into 2D SPIHT
Connectivity-Guided Adaptive Wavelet Transform based mesh compression framework is proposed. The transformation uses the connectivity information of the 3D model to exploit the inter-pixel correlations. Orthographic projection is used for converting the 3D mesh into a 2D image-like representation. The proposed conversion method does not change the connectivity among the vertices of the 3D model...
متن کاملAlgorithm-based low-power VLSI architecture for 2D mesh video-object motion tracking
This paper presents an algorithm-based low-power VLSI architecture for video object (VO) motion tracking. The new architecture uses a novel hierarchical adaptive structured mesh topology. The structured mesh offers a significant reduction in the number of bits that describe the mesh topology. The motion of the mesh nodes represents the deformation of the VO. The motion compensation is performed...
