Sliding-Window Designs for Vertex-Based Shape Coding  
Traditionally the sliding window (SW) has been employed in vertex-based operational rate distortion (ORD) optimal shape coding algorithms to ensure consistent distortion (quality) measurement and impr......

A Unified Approach of Bit-Rate Control for Binary and Gray-Level Shape Sequences Coding  
This paper describes a unified framework of bit-rate control for binary and gray-level shape coding. An exponential rate-distortion model is proposed for binary shape and used in the bit-rate control.......

Joint texture-shape optimization for MPEG-4 multiple video objects  
In this paper, we present a uniform framework for optimal multiple video object bit allocation in MPEG-4. We combine the rate-distortion (R-D) models for the texture and shape information of arbitrari......

Optimal bit allocation for MPEG-4 multiple video objects  
In this paper, we present an optimal bit allocation algorithm for multiple video objects (MVO's) in MPEG-4 video coding. We combine the rate-distortion models for texture and shape information to achi......

A Rate and Distortion Analysis of Multiscale Binary Shape Coding Based on Statistical Learning  
In this paper, we propose a statistical learning-based approach to analyze the rate-distortion characteristics of MPEG-4 multiscale binary shape coding. We employ the polynomial kernel function and ep......

New Dynamic Enhancements to the Vertex-Based Rate-Distortion Optimal Shape Coding Framework  
Existing vertex-based operational rate-distortion (ORD) optimal shape coding algorithms use a vertex band around the shape boundary as the source of candidate control points (CP) usually in combinatio......
