Improved Spatial Scalability For Video Compression
Journal Title: Acta Technica Napocensis- Electronica-Telecomunicatii (Electronics and Telecommunications) - Year 2012, Vol 53, Issue 1
Abstract
Spatial scalability (layering) in MPEG is not often used due to the lack of coding efficiency and available ICs. This work presents an alternative spatial scalability schemes that have better coding efficiency, and yet are relatively easy to implement with existing building blocks. Furthermore it presents experiments that have been conducted in order to improve the coding efficiency, and enable a backwards compatible HDTV DVD system. Attempts have been made to improve the spatial scalability of MPEG-2/MPEG-4.

Robust Feature Sets for the Speech Processing
This paper compares the various feature sets for speech signal such as cepstral-based and acoustically-driven parameters to analyze and see how robust they are in different noise environments. Despite the success of the...
A Functional Model for A Standalone Fingerprint Recognition System
Abstract: The paper describes a functional model for a standalone fingerprint recognition system, representing a minimum implementation to demonstrate the functionality of such system. For simplicity, the model uses only...

A Matlab GUI for Simulating the Propagation of the Electromagnetic Field in A 2-D Infinite Space
This paper presents a Matlab-based graphical user interface (GUI) that allows the simulation of the propagation of an electromagnetic wave in a 2-D infinite space. The homogeneous, isotropic medium is modeled by using th...
Performance Analysis of Network Coding-Based Cooperation Algorithms Employed in Cellular Networks
The employment of the network coding, combined with distributed FEC coding, in cooperative transmission schemes leads to a more efficient use of the additional time-frequency resources required by cooperation, i.e. by al...
