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 ...
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 ...
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 ...
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 ...
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 ...
Efficient parallelization on GPU of an image smoothing method based on a variational model
(2016-07-21)
Medical imaging is fundamental for improvements in diagnostic accuracy. However, noise frequently corrupts the images acquired, and this can lead to erroneous diagnoses. Fortunately, image preprocessing algorithms can ...
Quantitative fractography by digital image processing: NIH Image macro tools for stereo pair analysis and 3-D reconstruction
(Blackwell Science, 2001-10-01)
A set of NIH Image macro programs was developed to make qualitative and quantitative analyses from digital stereo pictures produced by scanning electron microscopes. These tools were designed for image alignment, anaglyph ...
Statistical analysis of texture in trunk images for biometric identification of tree species
(Springer, 2015-04-01)
The identification of tree species is a key step for sustainable management plans of forest resources, as well as for several other applications that are based on such surveys. However, the present available techniques are ...
