Variational Optical-flow Temporal Super-Resolution using Multiframes

Abstract (in Japanese) (See Japanese page) 
(in English) We developed a variational method for frame-rate up-conversion of optical flow fields, for up-conversion
of frame-rate of optical flow, we combine motion coherency in an image sequence and smoothness of the temporal
flow field. Since optical flow vectors define motion of each point in an image, we can construct interframe images
from low frame-rate image sequence using flow fields vectors. This implies that our method can be used to estimate
ego-motion from a low frame-rate image sequence obtained by a remote exploration.
