This paper presents a new technique for the creation of a sequence of mosaic images from an original video shot. A mosaic image represents, on a single image, the scene background seen all over the sequence and its creation requires the estimation of the warping parameters and the use of a blending technique. The warping parameters permit one to represent each original image in the mosaic reference. An estimation method, based on a direct comparison between the current original image and the previously calculated mosaic is proposed. A new analytic minimization criterion is also designed to optimize the determination of the blending coefficient used for the update of the mosaic image with a new original image. This criterion is based on constraints related to the temporal variations of the background, the temporal delay and the resolution of the created mosaic images, while its minimization can be analytically performed. Finally, the proposed method is applied to the creation of new video sequences in which the camera point of view, the camera focal, or the image size are modified. This approach has been tested and validated on real video sequences with large camera motion
