Abstract

Video bit rate reduction can be very important for all video streaming application. One of the possible ways to reduce bit rate is decreasing change in time or space domain i.e. changing frame rate or resolution. In this paper we present two no reference metrics mapping frame rate or resolution into MOS. Both models use simple to calculate parameters expressed by sequence spatial and temporal information. The models were estimated and verified upon distinctive video sequence sets. The considered frame rate change varies from 5 to 30 frames per second. The considered resolutions changes from SQCIF to SD.
