The issue of energy balancing in Wireless Sensor Networks is a pivotal one, crucial in their deployment. This problem can be subdivided in three areas: (i) energy conservation techniques, usually implying minimizing the cost of communication at the n

A parametric model for perceptual video quality estimation

Autor: J. Carlos López Ardao, Jose Joskowicz

Publikováno v: Telecommunication Systems. 49:49-62

In this paper, a parametric model is proposed which provides estimation for the perceived quality of video, coded with different codecs, at any bit rate and display format. The video quality metric used is one of the standardized Full Reference model
