Automatic segmentation of digital images applied in cardiac medical images
(2010-07-09)
The digital image processing has been applied in several areas, especially where it is necessary use tools for feature extraction and to get patterns of the studied images. In an initial stage, the segmentation is used to ...
Automated diagnosis of human intestinal parasites using optical microscopy images
(2013-08-22)
Intestinal parasitosis constitutes a serious health problem in most tropical countries. The diagnosis of enteroparasites in laboratory routine relies on the examination of stool samples using optical microscopy and the ...
Pitch detection algorithms based on zero-cross rate and autocorrelation function for musical notes
(2008-09-22)
This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ...
JSEG-based image segmentation in computer vision for agricultural mobile robot navigation
(2009-12-01)
This project aims to apply image processing techniques in computer vision featuring an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization ...
Fast automatic microstructural segmentation of ferrous alloy samples using optimum-path forest
(2010-05-21)
In this work we propose a novel automatic cast iron segmentation approach based on the Optimum-Path Forest classifier (OPF). Microscopic images from nodular, gray and malleable cast irons are segmented using OPF, and Support ...
Hydrodynamic Characterization of a Surface Storage Zone in a Natural Stream
(2015)
Flow developed in surface storage zones in rivers is very important for many physical and
biogeochemical processes. These regions are characterized by low velocities compared to the flow
in the main channel and long ...
