The authors previous use of this representation has focused on geometric recovery of scene static structure from the analysis of relative motions on the moving image plane. That earlier work (Int. J. of Comput. Vis., vol.2, no.1, p.51-72 (1989); p.33-50, (1989); vol.1, no.1, p.7-55 (1987)), exploited the implicit partitioning of motions along epipolar lines to enable search-free feature tracking and position estimation. The ST manifolds provide explicit information about feature 3D contiguity, and their use leads to the recovery of feature 3D position, object 3D contours, and scene 3D surfaces. The authors have turned their attention to the task of interpretating non-static scenes, and track and estimate motions of independently moving objects and background by their appearance and behavior on the ST surface. Selecting the most reliable and discriminating information in the scene, the system demonstrates robust feature tracking over a large range of feature sizes and velocities. When coupled with the more mature epipolar-plane image analysis system, this motion analysis capability will enable camera solving, dynamics tracking, and scene reconstruction within a unified framework.<<ETX>>","PeriodicalId":208481,"journal":{"name":"Proceedings of the IEEE Workshop on Visual Motion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scheme is motivated by psychophysical observations and designed to achieve efficient, robust and flexible behavior. The scheme consists of multiple interacting stages. At the structure-from-motion stage, relative depths and 3D velocities are estimated by minimizing the error in fit to the instantaneous 2D motion measurements and the overall deviation from rigidity. This nonlinear optimization is achieved by an efficient two-stage iterative algorithm. The temporal integration stage based on Kalman filtering effectively improves the 3D structure over multiple frames. The global motion of the observer or each constituent object can be computed at a later stage by using the estimated 3D velocities. The surface reconstruction stage reconstructs complete 3D surfaces, which can further stabilize the 3D structure recovery. The scheme can account for a number of psychophysical findings that include the perceptual demonstrations explored by Ramachandran et al. (Husain et al. 1989, Lappin et al. 1980) regarding interactions between two superimposed cylinders, and the experimental results using displays of moving points with short lifetimes (28, 55).<<ETX>>","PeriodicalId":208481,"journal":{"name":"Proceedings of the IEEE Workshop on Visual Motion","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131965793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
