Robust Motion Estimation for Camcorders Mounted in Mobile Platforms
Cai, Jinhai & Walker, Rodney A. (2008) Robust Motion Estimation for Camcorders Mounted in Mobile Platforms. In Digital Image Computing: Techniques and Applications (DICTA) 2008, 1-3 December 2008, Canberra, Australia.
In this paper, we propose a novel camera motion estimation algorithm for mobile platforms. Videos captured by cameras mounted in mobile platforms suffer from jitter motions caused by various factors. It is vital to obtain accurate estimates of camera motions in order to remove these undesirable jitters. But existing motion estimation methods for mobile platforms have difficulties to deal with the interference of moving objects and estimation errors. We propose to estimate camera motions from histograms of local motions as the position of the highest peak in each motion histogram is insensitive to estimation errors and robust to the interference of moving objects. We also propose to use sorted arrays to implement histograms due to its advantages. Experiments show our proposed methods can achieve promising results.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
