Journal ArticleDOI
A new approach for classification skin lesion based on transfer learning, deep learning, and IoT system
Douglas de A. Rodrigues,Roberto F. Ivo,Suresh Chandra Satapathy,Shuihua Wang,D. Jude Hemanth,Pedro Pedrosa Rebouças Filho +5 more
TL;DR: This work proposes the use of Transfer Learning and Deep Learning in an IoT system to assist doctors in the diagnosis of common skin lesions, typical nevi, and melanoma, and uses Convolutional Neural Networks (CNNs) as resource extractors.
Journal ArticleDOI
Fast fully automatic heart fat segmentation in computed tomography datasets.
Victor Hugo C. de Albuquerque,Victor Hugo C. de Albuquerque,Douglas de A. Rodrigues,Roberto F. Ivo,Solon Alves Peixoto,Tao Han,Wanqing Wu,Pedro Pedrosa Rebouças Filho +7 more
TL;DR: A new approach to the segmentation of cardiac fat from Computed Tomography (CT) images using a clustering algorithm called Floor of Log (FoL), which proves to be efficient, besides having good application times, and has the potential to be a medical diagnostic aid tool.
Journal ArticleDOI
New approach to evaluate a non-grain oriented electrical steel electromagnetic performance using photomicrographic analysis via digital image processing
Pedro Pedrosa Rebouças Filho,José Ciro dos Santos,Francisco Nélio Costa Freitas,Douglas de A. Rodrigues,Roberto F. Ivo,Luis Flavio Gaspar Herculano,Hamilton Ferreira Gomes de Abreu +6 more
TL;DR: In this article, a photomicrographic analysis was performed on non-grain oriented electrical steels with 1.28% silicon, cold-rolled with reductions of 50% and 70%, annealed in box at 730°C for 12h, and subjected to a subsequent annealing heat treatment for grain growth at 620°C, 730 Â c, 840 Â C and 900 ÂC for 1, 10, 100 and 1000 Â min at each temperature.
Journal ArticleDOI
Cascaded Volumetric Fully Convolutional Networks for Whole-Heart and Great Vessel 3D segmentation
Tao Han,Roberto F. Ivo,Douglas de A. Rodrigues,Solon Alves Peixoto,Victor Hugo C. de Albuquerque,Pedro Pedrosa Rebouças Filho +5 more
TL;DR: The proposed Cascaded Volumetric Fully Convolutional Networks enables the visualization and iteration of the segmented volume in 3D so that the doctor can analyze the entire structure of the heart along with the circulatory network.
Journal ArticleDOI
Fast fully automatic skin lesions segmentation probabilistic with Parzen window.
João Victor Souza das Chagas,Roberto F. Ivo,Matheus T. Guimarães,Douglas de A. Rodrigues,Elizângela de S. Rebouças,Pedro Pedrosa Rebouças Filho +5 more
TL;DR: The highlights of the proposed SPPW method of segmentation are its short average segmentation time per image, and its metrics values, which are often higher than the ones obtained by other methods.
