The method proposed formeasuring image velocity is based on the phase behavior in the outputof velocity-tuned filters. Extensive experimental work is used to showthat phase can be a reliable source of pure image translation, smallgeometric deformation, smooth contrast variations, and multiple localvelocities. Extensive theorectical analysis is used to explain therobustness of phase with respect to deviations from image translation,and to detect situations in which phase becomes unstable. The resultsindicate that optical flow may be extracted reliably for computingegomotion and structure from motion. .The monograph also contains a review of other techniques and frequencyanalysis applied to image sequences, and it | | 出版日期 | Book 1992 | | 关键词 | Interpolation; Optical flow; Tracking; behavior; machine vision; measurement; perception; reflection; stabil | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4615-3648-2 | | isbn_softcover | 978-1-4613-6623-2 | | isbn_ebook | 978-1-4615-3648-2Series ISSN 0893-3405 | | issn_series | 0893-3405 | | copyright | Springer Science+Business Media New York 1992 |
