Quincunx filter banks are two-dimensional, two-channel, nonseparable filter banks. They are widely used in many signal processing applications. In this thesis, we study the design and applications of quincunx filter
banks ...
Data-dependent triangulation (DDT) based mesh-generation schemes for image representation are studied. A flexible mesh-generation framework and a highly effective mesh-generation method that employs this framework are ...
Triangle meshes can provide an effective geometric representation of images. Although
many mesh generation methods have been proposed to date, many of them do not explicitly
take image discontinuities into consideration. ...
Triangle mesh models of images are studied. Through exploration, a computational framework for mesh generation based on data-dependent triangulations (DDTs) and two specific mesh-generation methods derived from this framework ...
Image coding is studied, with the work consisting of two distinct parts. Each part focuses on different coding paradigm.
The first part of the research examines subband coding of images. An optimization-based method for ...
A novel progressive lossy-to-lossless coding method is proposed for mesh
models of images whose underlying triangulations have arbitrary
connectivity. For a triangulation T of a set P of points, our proposed
method ...
