Optimal Bit Allocation in 3D Compression
To use 3D models on the Internet or in other bandwidth-limited applications, it is often necessary to compress their triangle mesh representations. We consider the problem of balancing two forms of lossy mesh compression: reduction of the number of vertices by simplification, and reduction of the number of bits of resolution used per vertex coordinate via quantization. Let A be a triangle mesh ...
متن کاملBit-allocation for Textured 3d Models
In this paper, we propose a bit-allocation algorithm to transmit textured 3D models over low bit-rate channels. Both the geometry and the texture are progressively and independently compressed. Distribution of the bit budget between mesh and texture is based on a novel distortion measure, which quantifies the perceptual difference resulting from simplifying the geometry or using a low-resolutio...
متن کاملOptimal bit allocation under multiple
We present a new Lagrangian-based iterative technique for rate{distortion optimization under multiple rate constraints. We show how for sets of \lin-ear" constraints this technique can be proven to be optimal up to a convex hull approximation. As an application we consider the problem of optimal buuer-constrained bit allocation. Our technique can be used to nd an excellent approximation to the ...
متن کاملOptimal bit allocation for low bit rate video streaming applications
Current rate control schemes in video coding standards do not have efficient frame-level bit allocation because of the inherent constraints in real-time encoding. In this paper, we assume an offline video encoding environment and proposed a rate control scheme based on optimal bit allocation for low bit rate streaming applications. Specifically, at the encoder, we code each video sequence in tw...
متن کاملOptimal bit allocation with side information
For a given set of quantizers and a data vector, the optimal bit allocation in a rate/distortion sense is the sequence of quantizers which minimizes the overall distortion for a given bit budget. In an operational framework, this sequence is dependent on the data realization rather than on its probabilistic model and the cost of describing the sequence itself becomes therefore part of the bit b...
