Abstract :
Super-resolution reconstruction (SRR) aims to 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 SRR uses a high accuracy registration algorithm, the fast affine block-based registration, in the maximum likelihood framework. Moreover, the BTV (bi-total variance) regularization is used to compensate the missing measurement information. The experimental results show that the proposed reconstruction can apply on real sequence such as Suzie
