OW-SLR: Overlapping Windows on Semi-Local Region for Image Super-Resolution

1 code implementation9 Nov 2023 Rishav Bhardwaj, Janarthanam Jothi Balaji, Vasudevan Lakshminarayanan

In this paper, we propose applying a new technique called Overlapping Windows on Semi-Local Region (OW-SLR) to an image to obtain any arbitrary resolution by taking the coordinates of the semi-local region around a point in the latent space.
