“…Traditionally studied in controlled laboratory experiments [4,8,26,42], such motion cues have received comparatively little attention for the purpose of object popout in computer vision, e.g. [3,7,29,34].…”

“…A particle filter approach is employed to deal with the complex, multi-modal distributions in the highdimensional state space. [8] uses local motion information only to infer boundaries and direction-of-figure. In [11], tensor voting yields optical flow estimates together with an uncertainty measure based on the homogeneity of the votes.…”

“…Occlusion boundaries are assumed to be maxima in the uncertainty measure. Neither [4], [8] nor [11] make use of static cues. Since the optical flow as a secondary feature requires integration over a spatial domain to deal with the aperture problem, edges based only on motion estimates are usually inaccurate and dislocated.…”
“…Another approach uses filters tuned to the local spatiotemporal image structure of a motion discontinuity [6,8,11]. These methods model image structure over time rather than the motion field.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
