1. A method for generating a super-resolution image from at least two input images represented by digital samples, the super-resolution image having a final resolution higher than an initial resolution of one of the at least two input images, the method comprising the following steps: obtaining, for each input image of the at least two input images, a distortion model to register the input image on a reference grid at the final resolution; warping each input image into a warped image according to the distortion model, comprising computing warped coordinates respectively for digital samples of the input image, wherein the contribution of each digital sample of the input image to the warped image is weighted, the weight applied to each digital sample depending on the warped coordinates of the digital sample; and combining the warped images in order to generate a combined warped image having the final resolution.
