Application of multifractal analysis to segmentation of water bodies in optical satellite images
(Paper in Physics, 2017-09)
In this paper, we study the characteristics of multifractal spectra obtained for remote sensing images through the coarse theory and propose a method for segmentation of water bodies based on it. In the first place, spectra ...
Microscope cell color images segmentation by fuzzy morphological reconstruction
(SPIE Digital Library, 2017-01-26)
There are many different methods to perform gray level segmentation in microscope cell images however, in some circumstances, texture features and roughness are not as relevant as the color for the segmentation task. In ...
An image processing pipeline to segment iris for unconstrained cow identification system
(De Gruyter, 2019-01)
One of the most evident costs in cow farming is the identification of the animals. Classic identification processes are labour-intensive, prone to human errors and invasive for the animal. An automated alternative is an ...
Multithresholding techniques in SAR image classification
(Elsevier Science, 2021-08)
Beyond bilevel segmentation, multithresholding (MT) is a powerful technique that is seldom considered in image analysis. In active imaging techniques, however, MT appears as a significant alternative due to its obliviousness ...
A variational shape optimization approach for image segmentation with a Mumford-Shah functional
(Society for Industrial and Applied Mathematics, 2008-12)
We introduce a novel computational method for a Mumford-Shah functional, which decomposes a given image into smooth regions separated by closed curves. Casting this as a shape optimization problem, we develop a gradient ...
Automatic design of aperture filters using neural networks applied to ocular image segmentation
(European Association for Signal Processing, 2014-09)
Aperture filters are image operators which combine mathematical morphology and pattern recognition theory to design windowed classifiers. Previous works propose designing and representing such operators using large decision ...
Polarimetric SAR Image Segmentation using CEM Algorithm
(Institute of Electrical and Electronics Engineers, 2014-08)
In this work we perform Synthetic Aperture Radar (SAR) polarimetric images segmentation based on the Classification-Expectation-Maximization (CEM) method, with both supervised and unsupervised initialization. In the former ...
Texture descriptors for robust SAR image segmentation
(Society of Photo-Optical Instrumentation Engineers, 2021-12-29)
SAR (synthetic aperture radar) and PolSAR (polarimetric synthetic aperture radar) images fulfill a fundamental role in Earth observation, due to their advantages over optical images. However, the presence of speckle noise ...
Intuitionistic fuzzy set and fuzzy mathematical morphology applied to color leukocytes segmentation
(Springer, 2019-10-25)
This work presents a new algorithm based on Atanassov’s intuitionistic fuzzy sets and fuzzy mathematical morphology to leukocytes segmentation in color images. The main idea is based on modeling a color image as an Atanassov’s ...
Lumen-intima and media-adventitia segmentation in IVUS images using supervised classifications of arterial layers and morphological structures
(Elsevier, 2019-08)
Background: Intravascular ultrasound (IVUS) provides axial grey-scale images of blood vessels. The large number of images require automatic analysis, specifically to identify the lumen and outer vessel wall. However, the ...
