A new computer vision-based approach to aid the diagnosis of Parkinson's disease
Clayton R. Pereira,Danillo Roberto Pereira,Francisco Assis da Silva,João P. Masieiro,Silke Anna Theresa Weber,Christian Hook,João Paulo Papa +6 more
TL;DR: It is observed that the main problem in detecting PD is the patients in the early stages, who can draw near-perfect objects, which are very similar to the ones made by control patients, leading to higher accuracies than spiral images.
Proceedings ArticleDOI
A Step Towards the Automated Diagnosis of Parkinson's Disease: Analyzing Handwriting Movements
Clayton R. Pereira,Danillo Roberto Pereira,Francisco Assis da Silva,Christian Hook,Silke Anna Theresa Weber,Luis A. M. Pereira,João Paulo Papa +6 more
TL;DR: Some results toward the automated diagnosis of PD by means of computer vision-based techniques in a dataset composed by dozens of patients are presented, which is one of the main contributions of this work.
Journal ArticleDOI
A New Method for Automatic Vehicle License Plate Detection
Guilherme Lofrano Corneto,Francisco Assis da Silva,Danillo Roberto Pereira,Leandro Luis de Almeida,Almir Olivete Artero,João Paulo Papa,Victor Hugo C. de Albuquerque,Helton Molina Sapia +7 more
TL;DR: A method for real time detection and segmentation of car license plates based on image analyzing and processing techniques is presented, showing that the computational cost and accuracy rate considered are acceptable to real time applications.
Journal ArticleDOI
Intrusion Detection System Based On Flows Using Machine Learning Algorithms
Eduardo Massato Kakihata,Helton Molina Sapia,Ronaldo Toshiaki Oiakawa,Danillo Roberto Pereira,João Paulo Papa,Victor Hugo C. de Albuquerque,Francisco Assis da Silva +6 more
TL;DR: This work presents an IDS that can perform the flow- based analysis (netflow) and aims at building a public dataset to be used by researchers worldwide in order to foster IDS-related research.
Journal ArticleDOI
ALPRS - A New Approach for License Plate Recognition using the Sift Algorithm
Francisco Assis da Silva,Almir Olivette Artero,Maria Stela Veludo de Paiva,Ricardo Luís Barbosa +3 more
TL;DR: A new approach for the automatic license plate recognition, which includes the SIFT algorithm in step to locate the plate in the input image, and the correspondence between the spatial orientations and the positioning associated with the keypoints is observed.
