A tool for displaying and analysis of video artifacts

Due to high capacity requirements, raw videos have to be compressed prior storage and transmission. However, compression and transmission processes introduce visible artifacts in video signal. Thus video quality needs to be monitored and evaluated continuously. In this work a new solution that enables the additional offline analysis of detected video artifacts is proposed. The solution is based on Real-time Audio and Video Artifacts Detection Tool (AVADT) and it displays the timeline accompanied by the markers of different artifacts in different moments of video stream. Furthermore, in the proposed solution the reproduction of video segments that contain detected artifacts is enabled. By using the proposed solution, video service providers can perform the extended analysis and check existing trends related to artifact occurrence during video streaming.
