A method for the realization of virtual depth of field

GENG Zhen-wei,TANG Xiao-an,CAI Xuan-ping  
Dynamically changing depth of field in real-time while making videos afterward or synthesizing images can even more enhance third dimension,but this make process via software very difficult,even bottleneck,so we adopt a pre-processing method that processing the foreground and background with low-pass filtering respec-tively in advance,After having gotten the foreground and background frame queue,we can adjust the position in the foreground queue and background queue respectively too,Just to confirm what the foreground and background should be in the end,then we combine the foreground and background dynamically to make the virtual depth in field effect.[
