Motion-Model-Based Boundary Extraction and a Real-Time Implementation

Periodic motion detection and segmentation via approximate sequence alignment

“…These methods find the period and classify periodic motion given the tracks of objects over time. While the methods in [16,12,5] rely on object segmentation, tracking and/or camera stabilization, the method in [21] does not assume segmentation and is more close to ours. It, however, has not been applied to scenes with moving camera and dynamic backgrounds.…”

“…Time-frequency analysis of image sequences was explored in [16,12,5,21]. These methods find the period and classify periodic motion given the tracks of objects over time.…”

“…It has been widely recognized as a powerful cue for detecting salient objects or gestures in video; see for example [20,16,12,5,13,21]. The focus of this paper is on leveraging the periodic motion of objects for a different, and thus far unexplored, purpose: motion segmentation.…”
