Abstract :
We propose an efficient method for creating a mosaic of a video sequence in the presence of moving objects. This method includes two principal processes. The first one removes the moving objects from the background, and as a side effect, obtains the global motion. This global motion provides a good initial estimation to the next stage. Second, we employ a feature-based technique to derive the precise global motion with eight projective parameters. The performance of our work is demonstrated by experiments
