In multimedia transmission, it is important to rely on an ob jective quality metric which accurately represents the sub jective quality of processed images and video sequences. Maintaining acceptab le Quality of Experience in video transmission requires the ab ility to measure the quality of the video seen at the receiver end. Reduced-reference metrics make use of side-information that is transmitted to the receiver for estimating the quality of the received sequence with low complexity. This

A novel reduced-reference video quality known as the Spatial Information in Salient Regions Reduced Reference Metric is proposed. The approach proposed ma kes use of spatial activity to estimate the received sequence distortion after concealment. The statistical elements analysed in this work are b ased on extracted edges and their luminance distributions. Results highlight that the proposed edge dissimilarit y measure has a good correlation with DMOS scores from the LIVE Video Datab ase.
