An iterative super-resolution reconstruction of image sequences using affine block-based registration

Super-resolution reconstruction produces one or a set of high-resolution (HR) images from a sequence of low-resolution (LR) images. Due to translational registration, super-resolution reconstruction can apply only on the sequences that have simple translation motion. This paper proposed a novel super-resolution reconstruction that that can apply on real sequences or complex motion sequences. The proposed super-resolution reconstruction uses a high accuracy registration algorithm, the fast affine block-based registration [16], in the maximum likelihood framework. Moreover, the regularization is used to compensate the missing measurement information. The experimental results show that the proposed reconstruction can apply on real sequence such as Foreman and Suzie.
