GEOMETRIC APPROACH TO IMPROVING ACTIVE PACKET LOSS MEASUREMENT-NETWORKING

Abstract: Measurement and estimation of packet loss characteristics are challenging due to the relatively rare occurrence and typically short duration of packet loss episodes. While active probe tools are commonly used to measure packet loss on end-to-end paths, there has been little analysis of the accuracy of these tools or their impact on the network. The objective of our study is to understand how to measure packet loss episodes accurately with end-to-end probes. ....etc

Packet loss concealment using audio morphing

Presented By:

Motivation


In packet data networks, excess traffic leads to delays or loss in delivery of information. In voice communication, long delays are intolerable and network delay budgets have strong influence on the design of packet voice systems.
To increase the tolerance of packet voice systems to lost packets some techniques have been developed.
These techniques do not use the a posteriori informati ....etc

Hi I am Jahnavi.I want to do project in image processing. I have selected the main topic like error concealment. I need some matlab programs for that related topic. I em trying to implement IEEE paper published in 2006, Adaptive MAP Error Concealment for Dispersively Packetized Wavelet-Coded Images.

Abstract—In this paper, we present an adaptive maximum a posteriori (MAP) rror concealment algorithm for dispersively packetized wavelet-coded images. We model the subbands of a waveletcoded image as Markov random fields, and use the edge ....etc

Cloaker: Hardware Supported Rootkit Concealment

Abstract
Rootkits are used by malicious attackers who desire to run software on a compromised machine without being de- tected. They have become stealthier over the years as a consequence of the ongoing struggle between ....etc

Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Piˇzurica, Member, IEEE, and Wilfried Philips, Member, IEEE



Abstract—

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into acco ....etc
