Abstract

Video Quality assessment is one of the most challenging problems in real time communications. Most of the quality assessment algorithms is based on pixels, so they are dependant of the original video as reference. This dependancy make complicated to apply these algorithms in a real time scenario. Besides, these algorithms do not consider Human Visual System characteristics. This paper introduces 3 algorithms that use HVS characteristics. The first two algorithms still use the original video as reference and the third uses only the received video as parameter.

Keywords: Video quality evaluation, HVS characteristics, FR and NR algorithms, resource consumption
