New adaptive interpolation schemes for efficient meshbased motion estimation

Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

Ranking DEA Efficient Units with the Most Compromising Common Weights

One may employ Data Envelopment Analysis (DEA) to discriminate decision-making units (DMUs) into efficient and inefficient ones base upon the multiple inputs and output performance indices. In this paper we consider that there is a centralized decision maker (DM) who ‘owns’ or ‘supervises’ all the DMUs. In such intraorganizational scenario the DM has an interest in discriminating the efficient ...

A Collaborative and Energy Efficient Data Routing Algorithm for Wireless Sensor Networks Through the Use of Game Theory

The proposed algorithm induces an energy-aware and efficient collaborative behaviour to the nodes using sensor centric information, by making them aware of their interdependency, without compromising the main purpose of the network the collection of information.

Bandwidth Efficient Coding for Error Control

One of the dramatic developments in bandwidth-efficient communications over the past few years is the introduction and rapid applications of combined coding and bandwidth efficient modulation, known as coded modulation, for error control. Using coded modulation, reliable data transmission can be attained without compromising bandwidth efficiency. In this report, we present the basic concepts of...

Cross-Layer Modeling Framework for Energy-Efficient Resilience

We describe a novel cross-layer, resiliencefocused integrated modeling framework. This is targeted to help define ultra energy-efficient embedded systems in the post-14nm CMOS design era, without compromising system-level resilience. The targeted application domain is represented by the suite of applications and kernels announced as part of the ongoing PERFECT program sponsored by DARPA MTO.
