Jiaqi Guo, Santiago Lopez-Tapia, Wing Shun Li +7
Computed tomography is a widely used imaging modality with applications ranging from medical imaging to material analysis. One major challenge arises from the lack of scanning info…
Real-World Atmospheric Turbulence Correction via Domain Adaptation
Xijun Wang, Santiago López-Tapia, Aggelos K. Katsaggelos
Atmospheric turbulence, a common phenomenon in daily life, is primarily caused by the uneven heating of the Earth's surface. This phenomenon results in distorted and blurred acquir…
Fast and Robust Cascade Model for Multiple Degradation Single Image Super-Resolution
Santiago López-Tapia, Nicolás Pérez de la Blanca
Single Image Super-Resolution (SISR) is one of the low-level computer vision problems that has received increased attention in the last few years. Current approaches are primarily…
A Single Video Super-Resolution GAN for Multiple Downsampling Operators based on Pseudo-Inverse Image Formation Models
Santiago López-Tapia, Alice Lucas, Rafael Molina +1
The popularity of high and ultra-high definition displays has led to the need for methods to improve the quality of videos already obtained at much lower resolutions. Current Video…
