Image Super-Resolution Using Generative Adversarial Networks with Learned Degradation Operators [PDF]

open access: yesMATEC Web of Conferences, 2022
Image super-resolution is a research endeavour that has gained notoriety in computer vision. The research goal is to increase the spatial dimensions of an image using corresponding low-resolution and high-resolution image pairs to enhance the perceptual ...

Pairwise Operator Learning for Patch Based Single-image Super-resolution [PDF]

open access: yes, 2016
Motivated by the fact that image patches could be inherently represented by matrices, single-image super-resolution is treated as a problem of learning regression operators in a matrix space in this paper. The regression operators that map low-resolution

SUPER-RESOLUTION OF MULTISPECTRAL IMAGES [PDF]

open access: yesModelling and Simulation in Science, 2007
In this paper we propose and analyze a globally and locally adaptive super-resolution Bayesian methodology for pansharpening of multispectral images. The methodology incorporates prior knowledge on the expected characteristics of the multispectral images uses the sensor characteristics to model the observation process of both panchromatic and ...

Image Super-Resolution Via Iterative Refinement

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2022
We present SR3, an approach to image Super-Resolution via Repeated Refinement. SR3 adapts denoising diffusion probabilistic models to conditional image generation and performs super-resolution through a stochastic denoising process. Inference starts with pure Gaussian noise and iteratively refines the noisy output using a U-Net model trained on ...

Microsphere super-resolution imaging [PDF]

open access: yes, 2016
Recently, it was discovered that microsphere can generate super-resolution focusing beyond diffraction limit. This has led to the development of an exciting super-resolution imaging technique -microsphere nanoscopy- that features a record resolution of 50 nm under white lights.

Super-resolution microscopy based on interpolation and wide spectrum de-noising

open access: yesКомпьютерная оптика, 2023
In the conventional single-molecule localizations and super-resolution microscopy, the pixel size of a raw image is approximately equal to the standard deviation of the point spread function.

Image Super-resolution Reconstruction Based on Sparse Representation and Guided Filtering [PDF]

open access: yesJisuanji gongcheng, 2018
In view of the fact that the image super-resolution reconstruction method cannot effectively reconstruct more high frequency image information in the process of image processing and storage,this paper proposes an image super-resolution reconstruction ...

Joint Image Reconstruction and Super-Resolution for Accelerated Magnetic Resonance Imaging

open access: yesBioengineering, 2023
Magnetic resonance (MR) image reconstruction and super-resolution are two prominent techniques to restore high-quality images from undersampled or low-resolution k-space data to accelerate MR imaging. Combining undersampled and low-resolution acquisition

Volatile-Nonvolatile Memory Network for Progressive Image Super-Resolution

open access: yesIEEE Access, 2021
Single-image super-resolution, i.e., reconstructing a high-resolution image from a low-resolution image, is a critical concern in many computer vision applications. Recent deep learning-based image super-resolution methods employ massive numbers of model
