Feature fusion quality assessment model for DASH video streaming
IET Image Processing, Volume 15, Issue 1, Page 127-142, January 2021., 2021 Abstract Dynamic Adaptive Streaming over HTTP (DASH) employs the flexible rate adaptation scheme to combat with time‐varying channel conditions. In addition to compression impairment, DASH video streaming suffers from transmission impairment, such as rate switches and stalling events.
