Based on our statistical investigation of a typical three-dimensional (3-D) wavelet codec, we
present a unified mathematical model to describe its operational rate-distortion (RD) …

Analytical modeling of the performance of video coders is essential in a variety of
applications, such as power-constrained processing, complexity-driven video streaming …

Based on our statistical investigation of a typical 3D (t+ 2D/2D+ t) wavelet codec, we present
a unified mathematical model to describe its rate-distortion (RD) behavior. We assess the …

Embedded coders provide a better rate-distortion tradeoff while the coded bit stream can be
truncated at any point without a significant perceptible distortion. We investigate rate control …

In our previous work, we have developed a rate-distortion (RD) modeling framework for H.
263 video coding by introducing the new concepts of characteristic rate curves and rate …

We present a framework for the systematic analysis of video encoding complexity, measured
in terms of the number of motion estimation (ME) computations, that we illustrate on motion …

Contrary to the conventional paradigm of transform decomposition followed by quantization,
we investigate the computation of two-dimensional (2D) discrete wavelet transforms (DWT) …

New results on scalable video-coding techniques are presented. Instead of the classical 3-D
discrete wavelet transform (DWT) decomposition paradigm that is often proposed in the …

Real-time rate-control for wavelet image coding requires characterization of the rate
required to code quantized wavelet data. An ideal robust solution can be used with any …

Computer applications, audio devices, and Video devices based on digital data technology
continue to appear in the marketplace. In response, the need for presenting audio and Video …
