A new family of orthonormal wavelet bases
A. Divakaran,William A. Pearlman +1 more
TL;DR: In this article, the wavelet scaling function that has the best combined time-frequency localization of all members of this family is found, and it is suggested that power complementary QMFs are sufficiently regular in practice.
Improving Compression Efficiency with Color Model Correlation based Cluster Coding in Visual Sensor Networks
Frederick Wilson Wheeler,William A. Pearlman,Chun-Ling Yang,Lai-Man Po,Chun-Ho Cheung,Kwok-Wai Cheung,Huaming Wu,Alhussein A. Abouzid,Dong-U Lee,Hyungjin Kim,Mohammad Rahimi,John Villasenor,Mohsen Nasri,Abdelhamid Helali,Halim +14 more
TL;DR: In this paper, the correlation between the color channels is used to propose the new algorithm that contains YCbCr color space model and the size of the image with each iteration level is analyzed.
A survey of the stateof-theart and utilization of embedded, treebased coding
William A. Pearlman,Amir Said +1 more
TL;DR: This work explores the development of tree-based, embedded image coding, their use with different image transformations, the reasons for their effectiveness and low complexity, their flexibility and incorporation into state-of-the-art compression systems.

Capacity of Steganographic Channels
TL;DR: This work investigates a central problem in steganography, that is: How much data can safely be hidden without being detected, and a formal definition of steganographic capacity is presented.
