DOI: 10.1109/lsp.2023.3259820
Abstract: In this letter, we propose a learned scale-arbitrary image downscaling method to downscale high-resolution (HR) images to a target low-resolution (LR) where it could be well upscaled by traditional simple upscaling methods. Specifically, the scale… read more here.

DOI: 10.1109/tip.2017.2772838
Abstract: In this paper, we propose a novel $L_{0}$ -regularized optimization framework for image downscaling. The optimization is driven by two $L_{0}$ -regularized priors. The first prior, gradient-ratio prior, is based on the observation that the… read more here.
