Abstract
This paper presents an approach to the analysis of multi­
ple motions in video, which combines frequency and spatial
domain information in a new manner. The tasks of interest
are finding the number of moving objects, velocity estima­
tion, object tracking, and motion segmentation. We propose
a novel, hybrid approach, which avoids problems of spatial
domain methods, like sensitivity to illumination changes or
great computational cost, but also uses spatial information
for precise object localization. Experiments with synthetic
and real sequences, show both the possibilities and limita­
tions of this approach.
