Super-resolution reconstruction in MRI

2012
Improving the resolution in magnetic resonance imaging (MRI) is always done at the expense of either the signal-to-noise ratio (SNR) or the acquisition time. This study investigates whether so-called super-resolution reconstruction (SRR) is an advantageous alternative to direct high-resolution (HR) acquisition in terms of the SNR and acquisition time ...

HOS-Based Image Super-Resolution Reconstruction

2007
In this paper a novel high-order statistics (HOS) based regularized algorithm for image super-resolution reconstruction is proposed. In this method, the image is divided into various regions according to the local forth order statistics. The segmentation label is then used to determine the weighted operator of the regularization term.

Super-resolution reconstruction of an image

Proceedings of 19th Convention of Electrical and Electronics Engineers in Israel, 2002
This paper presents a generalization of restoration theory for the problem of super-resolution reconstruction (SRR) of an image. In the SRR problem, a set of low quality images is given, and a single improved quality image which fuses their information is required.

Super-resolution reconstruction using nonlocal means

Optics and Precision Engineering, 2013
As conventional super-resolution algorithms can not implement the motion estimation and reconstruction for an image with local motion in practical engineering applications,this paper proposed a super-resolution reconstruction algorithm based on NonLocal Means(NLM).First,the NLM filter,one of the successful denoising filters in recent years,was ...
