Reference Based Face Super-Resolution

IEEE Access, 2019
Despite the great progress of image super-resolution in recent years, face super-resolution has still much room to explore good visual quality while preserving original facial attributes for larger up-scaling factors.

Super-resolution far-field ghost imaging via compressive sampling

, 2011
Much more image details can be resolved by improving the system's imaging resolution and enhancing the resolution beyond the system's Rayleigh diffraction limit is generally called super-resolution.

Super-resolution image transfer by a vortex-like metamaterial [PDF]

, 2013
We propose a vortex-like metamaterial device that is capable of transferring image along a spiral route without losing subwavelength information of the image. The super-resolution image can be guided and magnified at the same time with one single design.

Light Field Super-Resolution Via Graph-Based Regularization

, 2017
Light field cameras capture the 3D information in a scene with a single exposure. This special feature makes light field cameras very appealing for a variety of applications: from post-capture refocus, to depth estimation and image-based rendering ...

Structured illumination lensless digital holographic microscopy (SI-LDHM)

Frontiers in Physics
In this work, we propose a structured-illumination lensless digital holographic microscopy (SI-LDHM). SI-LDHM illuminates a sample with 24 structured illuminations (8 orientations × 3 phase shifts) and records the defocused interferogram formed by two ...

Medical Video Super-Resolution Based on Asymmetric Back-Projection Network With Multilevel Error Feedback

IEEE Access, 2021
Medical video is important for medical diagnosis. However, due to the influence of the network bandwidth and hardware equipment, some medical videos have low resolution, which is not conducive for diagnosing early diseases with small lesions.

Deep Neural Network for Image Super Resolution Driven by Prior Denoising

Nantong Daxue xuebao. Ziran kexue ban, 2021
In order to improve image super resolution, a double layer convolution neural network in image denoising is embedded in image restoration tasks. The image super resolution method driven by prior denoising with deep neural network is proposed.

Phaseless super-resolution in the continuous domain

, 2016
Phaseless super-resolution refers to the problem of superresolving a signal from only its low-frequency Fourier magnitude measurements. In this paper, we consider the phaseless super-resolution problem of recovering a sum of sparse Dirac delta functions ...
