Fast identification of individuals based on iris characteristics for biometric systems
(2012-02-13)
Nowadays, systems based on biométrie techniques have a wide acceptance in many different areas, due to their levels of safety and accuracy. A biometrie technique that is gaining prominence is the identification of individuals ...
Color description of low resolution images using fast bitwise quantization and border-interior classification
(Institute of Electrical and Electronics Engineers - IEEEBrisbane, 2015-04)
Image classification often require preprocessing and feature extraction steps that are directly related to the accuracy and speed of the whole task. In this paper we investigate color features extracted from low resolution ...
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 ...
Long-term Satellite Image Time Series for the Assessment of Land Use/Cover Change in the Brazilian Amazon Rainforest
(Spie-int Soc Optical Engineering, 2018-01-01)
The regular acquisition of Earth Observations by remote sensing satellites provides long-term Satellite Image Time Series (SITS). Land surface spectral variability provides the capacity for the assessment of Land Use/Cover ...
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 ...
A low-power silicon-on-insulator PWM discriminator for biomedical applications
(Institute of Electrical and Electronics Engineers (IEEE), 2000-01-01)
A CMOS/SOI circuit to decode PWM signals is presented as part of a body-implanted neurostimulator for visual prosthesis. Since encoded data is the sole input to the circuit, the decoding technique is based on a double-integration ...
A fast histogram equalization and KDE to aid a supervised algorithm to count Eucalyptus seedlings
(2020-12-01)
In a previous work, we developed two supervised approaches for automatic seedling counting in a UAV high-definition image from an Eucalyptus plantation stand of approximately 62 acres. We observed that the deployment of ...
A 2D Deep Boltzmann Machine for Robust and Fast Vehicle Classification
(2017-11-03)
The visual and automatic classification of vehicles plays an important role in the Transport Area. Besides of security issues, the monitoring of the type of traffic in streets and highways, as well the traffic dynamics ...
Geometric modeling from the medical images in the CAD system to support prosthesis design
(2010-12-01)
This paper presents an individual designing prosthesis for surgical use and proposes a methodology for such design through mathematical extrapolation of data from digital images obtained via tomography of individual patient's ...
