Paper in ICCV 2011: "Gaussian Process Regression Flow for Analysis of Motion Trajectories"
Paper/Citation Abstract Analysis and Recognition of motions and activities of objects in videos requires effective representations for analysis and matching of motion trajectories. In this paper, we introduce a new representation speciﬁcally aimed at matching motion trajectories. We model a trajectory as a continuous dense ﬂow ﬁeld from a sparse set of vector sequences using […]

Paper in ICCV 1999: "Motion Based Decompositing Video"
Motion Based Decompositing Video [bibtex file=IrfanEssaWS.bib key=1999-Brostow-MBDV] Abstract We present a method to decompose video sequences into layers that represent the relative depths of complex scenes. Our method combines spatial information with temporal occlusions to determine relative depths of these layers. Spatial information is obtained through edge detection and a customized contour completion algorithm. Activity […]
