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.
