A survey on some measurement methods for subjective video quality assessment

Abstract

There are a lot of subjective video quality assessment methods (SSNCS, SSCQE, DSCQS, DSIS, PC, ACR, etc.) for a wide variety of application (digital TV, video surveillance, object recognition, overall video quality, compression artifacts and transmission technology impairment level, etc.), so they need to be listed, structured and classified. The goal of the paper is a brief survey of measurement methods for subjective video quality assessment. Firstly, the methods classification is given, secondly, a generalized analysis of crowd-based questionnaire measurement data (1265 observers, 738 women and 527 men, aged from 11 to 85) is presented. The results show that most observers preferred two-screen double stimulus as a simpler and more comfortable method compared to one-screen single stimulus method, but in contrast statistical calculations show that there are very strong correlation (0,93) between the both methods. In the further research it is necessary to experimentally measure and analyze which of these methods are statistically most reliable and repeatable.
