Techniques of medical image processing and analysis accelerated by high-performance computing: a systematic literature review
(2017-11-16)
Techniques of medical image processing and analysis play a crucial role in many clinical scenarios, including in diagnosis and treatment planning. However, immense quantities of data and high complexity of the algorithms ...
Computational methods for the image segmentation of pigmented skin lesions: A review
(Elsevier B.V., 2016-07-01)
Background and objectives: Because skin cancer affects millions of people worldwide, computational methods for the segmentation of pigmented skin lesions in images have been developed in order to assist dermatologists in ...
Morphology of flux avalanches in patterned superconducting films
(2013-06-01)
It is well known that under certain circumstances, magnetic fields applied perpendicularly to the plane of superconducting films can trigger flux avalanches. In such cases, the penetration has a tree-like profile. However, ...
Proposição de rotina morfológica para detecção de malha viária em imagens orbitais
(2010-01-01)
The outdating of cartographic products affects planning. It is important to propose methods to help detect changes in surface. Thus, the combined use of remote sensing image and techniques of digital image processing has ...
Evaluation epidermal p53 immunostaining by digital image analysis
(2013-02-01)
Digital techniques have been developed and validated to assess semiquantitatively immunohistochemical nuclear staining. Currently visual classification is the standard for qualitative nuclear evaluation. Analysis of pixels ...
Mapping low- and high-density clouds in astrophysical nebulae by imaging forbidden line emission
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Emission line ratios have been essential for determining physical parameters such as gas temperature and density in astrophysical gaseous nebulae. With the advent of panoramic spectroscopic devices, images of regions with ...
Geometric Filtering of Matches Between Points in Bands of Hyperspectral Cubes
(Ieee-inst Electrical Electronics Engineers Inc, 2019-03-01)
Hyperspectral images can present low contrast, noisy pixels, and illumination variation among bands, which complicates the extraction of interest points and reduces the number of reliable image matches affecting subsequent ...
Development of phantom for radiographic image optimization of standard patient in the lateral view of chest and skull examination
(Elsevier B.V., 2006-12-01)
We present the construction of a homogeneous phantom to be used in simulating the scattering and absorption of X-rays by a standard patient chest and skull when irradiated laterally. This phantom consisted of Incite and ...
Fast Transforms for Acoustic Imaging-Part I: Theory
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
The classical approach for acoustic imaging consists of beamforming, and produces the source distribution of interest convolved with the array point spread function. This convolution smears the image of interest, significantly ...
Generating Segmented Quality Meshes from Images
(SPRINGER, 2009)
Techniques devoted to generating triangular meshes from intensity images either take as input a segmented image or generate a mesh without distinguishing individual structures contained in the image. These facts may cause ...
