Implementation of a metric for video quality evaluation
 Kachlík, Miloš ; Dostál, Petr (referee) ; Slanina, Martin (advisor)
The aim of this work is to create a program able to implement the metric CPqD-IES to evaluate the quality of video in system MATLAB. This metric is described in Recommendation ITU-R BT.1683 for objective video quality measurement techniques for standard definition digital broadcast television with presence of a full reference. Video quality assessment is calculated objective parameters based on image segmentation. Natural scenes are segmented into edge, plane and texture regions. Objective parameters are assigned to each of these contexts. The relationship between each objective parameter and a subjective impairment level is approximated by the logistic curve, which is resulting in an estimated impairment level for each parameter.
