TLDR
This paper investigates the best permutation strategy for temporal, vertical, and horizontal filtering to minimize the requirement of delay elements and finds that the results are opposite to the authors' expectation.Abstract:
Since three-dimensional (3-D) subband coding has been introduced, most researches on 3-D subband coding perform temporal filtering first. In this paper, however, we investigate the best permutation strategy for temporal, vertical, and horizontal filtering to minimize the requirement of delay elements and find that the results are opposite to our expectation.read more

Subband coding of images
John W. Woods,S. O'Neil +1 more
TL;DR: A simple yet efficient extension of this concept to the source coding of images by specifying the constraints for a set of two-dimensional quadrature mirror filters for a particular frequency-domain partition and showing that these constraints are satisfied by a separable combination of one-dimensional QMF's.

Three-dimensional subband coding of video
TL;DR: The results of video coding based on a three-dimensional spatio-temporal subband decomposition are competitive with traditional video coding techniques and provide the motivation for investigating the 3-D subband framework for different coding schemes and various applications.

Digital coding of speech in sub-bands
TL;DR: A rationale is advanced for digitally coding speech signals in terms of sub-bands of the total spectrum, which provides a means for controlling and reducing quantizing noise in the coding.

Chun-Hsien Chou,Chi-Wei Chen +1 more
TL;DR: Simulation results show that acceptable visual quality can be maintained in transmitting video sequences with low bit rates over the wireless channel of high error rates, and the distortion due to erroneous transmission of coded data can be effectively suppressed.
