|Title:||Video artefacts in mobile imaging devices||Authors:||LOKE MEI HWAN||Keywords:||Video Artefacts, System Analysis, Video Processing, Image Quality Analysis||Issue Date:||4-Aug-2010||Citation:||LOKE MEI HWAN (2010-08-04). Video artefacts in mobile imaging devices. ScholarBank@NUS Repository.||Abstract:||For various lossy video compression and network transmissions systems, video artefacts are introduced during the process. As image quality is perceived by the human observer, it would be ideal if only those video artefacts that are discernable to human eyes are detected during quality evaluation. Such quality evaluation requires much computational power and careful understanding of the human visual sensitivity towards these video artefacts. This work involves a study of the human visual sensitivity towards video artefacts on mobile imaging devices. In our experiments, we evaluate the sensitivity of fifteen users towards some common video artefacts using a database of test video sequences recorded off the screen of a PDA device. Our results show that the human eye is very sensitive to spatial content loss and its sensitivity towards ?blockiness? is dependent on video content.||URI:||http://scholarbank.nus.edu.sg/handle/10635/20985|
