Improving optical flow on a pyramidal level
WitrynaInspired by the successes of deep learning in high-level vision tasks, Dosovitskiy et al. [8] propose two CNN models for optical flow, i.e., FlowNetS and FlowNetC, and introduce a paradigm shift to this fundamental low/middle-level vi-sion problem. Their work shows the feasibility of directly estimating optical flow from raw images using a ... WitrynaThe detection of moving objects in images is a crucial research objective; however, several challenges, such as low accuracy, background fixing or moving, ‘ghost’ …
