Abstract

Spatial Information (SI) and Temporal Information (TI) have been used widely as an approximate estimation of video complexity. Recently, SI (and TI) have found use in many other applications such as Quality of Experience modeling, Bandwidth and Rate-distortion modeling, etc., for both traditional and non-traditional (gaming, dynamic vision sensors, etc.) videos. A systematic study on SI and TI for videos, investigating the effect of different video encoding and processing steps has been missing so far. Also, SI and TI estimation has been limited to 8-bit videos, while there has been increasing popularity and usage of 10-bit videos. Towards this end, we present in this paper a comprehensive evaluation of the variation of SI and TI for different 8-bit and 10-bit videos. The effects of encoders, encoding settings, temporal pooling, resolution, etc. on SI and TI are presented in this study.
