Reduce Noise in Computed Tomography Image using Adaptive Gaussian Filter [PDF]
arXiv, 2019 One image processing application that is very helpful for humans is to improve image quality, poor image quality makes the image more difficult to interpret because the information conveyed by the image is reduced. In the process of the acquisition of medical images, the resulting image has decreased quality (degraded) due to external factors and ...

Real-Time Visual Navigation in Huge Image Sets Using Similarity Graphs [PDF]
arXiv, 2019 Nowadays stock photo agencies often have millions of images. Non-stop viewing of 20 million images at a speed of 10 images per second would take more than three weeks. This demonstrates the impossibility to inspect all images and the difficulty to get an overview of the entire collection.

Three dimensional rotational angiography imaging of double aortic arch vascular ring [PDF]
, 2013 Three dimensional (3D) rotational angiography is a technique used increasingly for imaging in congenital heart disease. Here the use of this technique for imaging of double aortic arch vascular ring is described and the advantages of this modality. are

Three‐dimensional strain‐rate imaging
Magnetic Resonance in Medicine, 1996 AbstractStrain‐rate imaging uses large velocity encoding gradients to obtain measurements of velocity that are extremely insensitive to the effects of random noise. The spatial differential of velocity yields the velocity gradient from which the strain‐rate and twist‐rate tensors can be determined. These tensors represent the distortion of the material

Super-resolution single-beam imaging via compressive sampling [PDF]
arXiv, 2010 Based on compressive sampling techniques and short exposure imaging, super-resolution imaging with thermal light is experimentally demonstrated exploiting the sparse prior property of images for standard conventional imaging system. Differences between super-resolution imaging demonstrated in this letter and super-resolution ghost imaging via ...

A self-consistent framework to study magnetic fields with strong gravitational lensing and polarised radio sources [PDF]
arXivWe introduce a unified approach that, given a strong gravitationally lensed polarised source, self-consistently infers its complex surface brightness distribution and the lens galaxy mass-density profile, magnetic field and electron density from interferometric data.

Snapshot multispectral imaging using a filter array [PDF]
International Workshop on Image Sensors and Imaging Systems
(IWISS2018), 2018 A multispectral filter array (MSFA) is one solution for capturing a multispectral image (MSI) in a single shot at low cost. We introduce our optimization method of the spectral sensitivity of the MSFAs and demosaicking, and show a new prototype filter array for snapshot imaging based on a photonic crystal.

High-resolution three-dimensional imaging radar [PDF]
, 2010 A three-dimensional imaging radar operating at high frequency e.g., 670 GHz, is disclosed. The active target illumination inherent in radar solves the problem of low signal power and narrow-band detection by using submillimeter heterodyne mixer receivers.
