| Summary: | In multimedia transmission, it is important to rely on an objective quality metric which accurately
represents the subjective quality of processed images and video sequences. Maintaining acceptable
Quality of Experience in video transmission requires the ability 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 attribute enables
real-time assessment and visual degradation detection caused by transmission and compression errors. A
novel reduced-reference video quality known as the Spatial Information in Salient Regions Reduced
Reference Metric is proposed. The approach proposed makes use of spatial activity to estimate the
received sequence distortion after concealment. The statistical elements analysed in this work are based
on extracted edges and their luminance distributions. Results highlight that the proposed edge dissimilarity
measure has a good correlation with DMOS scores from the LIVE Video Database. |
