Video mosaic is to make a wide or a panoramic image from video sequence by assembling the individual overlapping video frames. In this paper a technique is presented for video mosaic, which employs block matching based on phase correlation and robust M-estimation method. Initial point correspondences between each pair of consecutive frames are computed by block matching method based on phase correlation, then M-estimation method is used to identify and reject outliers and the alignment parameters between the consecutive frames is subsequently estimated by Levenberg-Marquardt iterative nonlinear minimization algorithm. Some mosaic examples are constructed to testify the availability of this approach.
