Super-resolution in high-contrast media

Super - High Resolution Vision System

Accompanying the development of various highly technological materials, electronics and printing techniques advancing towards super-high precision and density, demands are progressively increasing for precisely automated visual inspections in their manufacturing processes. Despite these demands, inspections of printed patterns, sheet surfaces and semiconductors, in which defects on rather large...

Time Reversal Super Resolution in Randomly Layered Media

In this paper we extend the range of applications of the previous work [Fouque et al, Wave Motion 42, 238-260 (2005)]. We consider first the case of an active source embedded below the surface in a finely layered random medium. We perform time reversal with a time reversal mirror placed at the surface and we consider here the case where this mirror is larger than the carrier wavelength. In cont...

High-resolution 3d Diffusion Mri: Detection of Lipid-rich Necrotic Core in Plaques without Contrast Media

Purpose: Large lipid-rich necrotic core (LRNC) is a well-known feature of rupture-prone atherosclerotic plaque , which is the major cause of both stroke and transient ischemic attack. Plaque lipid content has also been used clinically to monitor disease progression and the results of therapeutic interventions. Although contrast-enhanced (CE) MRI was shown possible for LRNC detection, patients w...

Robust Fuzzy Content Based Regularization Technique in Super Resolution Imaging

Super-resolution (SR) aims to overcome the ill-posed conditions of image acquisition. SR facilitates scene recognition from low-resolution image(s). Generally assumes that high and low resolution images share similar intrinsic geometries. Various approaches have tried to aggregate the informative details of multiple low-resolution images into a high-resolution one. In this paper, we present a n...
