AI-powered image upscalers are transforming how creatives, photographers, and marketers enhance low-resolution visuals. Unlike traditional methods, these tools use deep learning to reconstruct details ...

Abstract: This paper presents example-based methods for super-resolution (SR) reconstruction from a single set of low-resolution projections (or a sinogram) in positron emission tomography (PET).

Digital image sensors (DIS), devices that capture images by converting light patterns into electrical signals, are integrated ...

Abstract: Light field camera usually sacrifice spatial resolution for increasing angular resolution. Although it can capture rich spatial and angular information, leads to the spatial resolution ...
