Super-Resolution Blind Channel Modeling [PDF]

open access: yes2011 IEEE International Conference on Communications (ICC), 2011
In this work, we propose a super-resolution blind channel modeling algorithm to characterize wide-band channels comprised of disjoint frequency subbands. Since sounding signals are not available over the frequency guard bands separating adjacent subbands, conventional channel modeling methods suffer from poor performance in modeling the channel ...

Deep Blind Video Super-resolution

open access: yesCoRR, 2020
Existing video super-resolution (SR) algorithms usually assume that the blur kernels in the degradation process are known and do not model the blur kernels in the restoration. However, this assumption does not hold for video SR and usually leads to over-smoothed super-resolved images.

Deep Blind Super-Resolution for Satellite Video

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2023
Recent efforts have witnessed remarkable progress in Satellite Video Super-Resolution (SVSR). However, most SVSR methods usually assume the degradation is fixed and known, e.g., bicubic downsampling, which makes them vulnerable in real-world scenes with multiple and unknown degradations.

Medical image blind super‐resolution based on improved degradation process

open access: yesIET Image Processing, 2023
Clinical diagnosis has high requirements for the resolution of medical images, but most existing medical images super‐ resolution (SR) methods are performed under a known or specific degradation kernel.

Evaluating Deep Learning Techniques for Blind Image Super-Resolution within a High-Scale Multi-Domain Perspective

open access: yesAI, 2023
Despite several solutions and experiments have been conducted recently addressing image super-resolution (SR), boosted by deep learning (DL), they do not usually design evaluations with high scaling factors.

Mathematical theory of blind super-resolution: multidimensional cases [PDF]

open access: yes, 2021
Super-resolution is a fundamental problem in signal processing that concerns with extracting fine-scale data from low-resolution information. In this thesis, we focus on developing atomic norm-based algorithms for blind super-resolution. Due to the extra

Multi-Frame Blind Super-Resolution Based on Joint Motion Estimation and Blur Kernel Estimation

open access: yesApplied Sciences, 2022
Multi-frame super-resolution makes up for the deficiency of sensor hardware and significantly improves image resolution by using the information of inter-frame and intra-frame images.

Spatiotemporal super-resolution for low bitrate H.264 video [PDF]

open access: yes, 2010
Super-resolution and frame interpolation enhance low resolution low-framerate videos. Such techniques are especially important for limited bandwidth communications. This paper proposes a novel technique to up-scale videos compressed with H.264 at low bit-

Super-Resolution Microscopy: A Virus’ Eye View of the Cell [PDF]

open access: yes, 2014
It is difficult to observe the molecular choreography between viruses and host cell components, as they exist on a spatial scale beyond the reach of conventional microscopy.
