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......
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.......
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......
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......
The authors develop an object-based rate control algorithm for MPEG-4 arbitrarily shaped video object coding. There are three main contributions. An improved quadratic rate-distortion model for textur......
Geometric distortion measurement and the associated metrics involved are integral to the Rate Distortion (RD) shape coding framework, with importantly the efficacy of the metrics being strongly influe......
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......
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......
In this paper, we propose a statistical learning based approach to analyze the rate-distortion characteristics of MPEG-4 binary shape coding. We employ the polynomial kernel function and -insensitive......
