Mosaic images provide an efficient representation of image sequences and simplify scene exploration and analysis. However, the application of conventional methods to generate mosaics of scenes with moving objects causes integration errors and a loss of dynamic information. In this paper a method to compute mosaics of dynamic scenes is presented addressing the above mentioned problems. Moving pixels are detected in the images and not integrated in the mosaic yielding a consistent representation of the static scene background. Furthermore, dynamic object information is extracted by tracking moving regions. To account for unavoidable variances in region segmentation topologically neighboring regions are grouped into sets before tracking. The regions' and objects' motion characteristics are described by trajectories. Along with the background mosaic they provide a complete representation of the underlying scene which is idealy suited for further analysis.
