mapSR: A Deep Neural Network for Super-Resolution of Raster Map

open access: yesISPRS International Journal of Geo-Information, 2023
The purpose of multisource map super-resolution is to reconstruct high-resolution maps based on low-resolution maps, which is valuable for content-based map tasks such as map recognition and classification.

Accuracy and precision in super-resolution MRI: Enabling spherical tensor diffusion encoding at ultra-high b-values and high resolution

open access: yesNeuroImage, 2021
Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths.

Super-resolution reconstruction of rock CT images based on Real-ESRGAN

open access: yesGong-kuang zidonghua, 2023
Due to factors such as image acquisition equipment and geological environment, rock CT images have low resolution and unclear details. However, existing image super-resolution reconstruction methods are prone to losing details when characterizing high ...

Real-time single image and video super-resolution using an efficient sub-pixel convolutional neural network [PDF]

open access: yes, 2016
Recently, several models based on deep neural networks have achieved great success in terms of both reconstruction accuracy and computational performance for single image super-resolution. In these methods, the low resolution (LR) input image is upscaled

Single image super resolution via sparse reconstruction [PDF]

open access: yesSPIE Proceedings, 2012
High resolution sensors are required for recognition purposes. Low resolution sensors, however, are still widely used. Software can be used to increase the resolution of such sensors. One way of increasing the resolution of the images produced is using multi-frame super resolution algorithms. Limitation of these methods are that the reconstruction only

FRESH – FRI-based single-image super-resolution algorithm [PDF]

open access: yes, 2016
In this paper, we consider the problem of single image super-resolution and propose a novel algorithm that outperforms state-of-the-art methods without the need of learning patches pairs from external data sets.

Single image super resolution via neighbor reconstruction [PDF]

open access: yesPattern Recognition Letters, 2019
Super Resolution (SR) is a complex, ill-posed problem where the aim is to construct the mapping between the low and high resolution manifolds of image patches. Anchored neighborhood regression for SR (namely A+  [27]) has shown promising results. In this paper we present a new regression-based SR algorithm that overcomes the limitations of A+ and ...
