%X This paper introduces the use of a 2D parametric motion model to reduce noise in image sequences. We estimate with a robust method an affine motion model, accounting for the dominant image motion, and then cancel it before applying an adaptive spatio-temporal filter. We have compared the performance of several filtering schemes and evaluated the influence of the motion compensation step on this performance, including the comparison to the use of a dense motion field. We then apply on the denoised image sequence a low cost scheme to reconstruct high resolution images. This scheme is derived from an iterative backprojection algorithm. We again exploit the parametric motion model to keep a good trade-off between accuracy and computation time
