Going deeper into copy-move forgery detection
TL;DR: This work presents a new approach toward copy-move forgery detection based on multi-scale analysis and voting processes of a digital image and compares the proposed method to 15 others from the literature and reports promising results.
Journal ArticleDOI
Open set source camera attribution and device linking
TL;DR: New algorithms for open set modes of image source attribution and device linking are introduced and rely on a new multi-region feature generation strategy that models the decision space of a trained SVM classifier by taking advantage of a few known cameras to adjust the decision boundaries to decrease false matches from unknown classes.
Journal ArticleDOI
Application-Oriented Retinal Image Models for Computer Vision.
Ewerton Silva,Ricardo da Silva Torres,Allan Pinto,Lin Tzy Li,José Eduardo S. Vianna,Rodolfo Azevedo,Siome Goldenstein +6 more
TL;DR: This study proposes Application-Oriented Retinal Image Models that define a space-variant configuration of uniform images and contemplate requirements of energy consumption and storage footprints for CV applications, and hypothesizes that these models might decrease energy consumption in CV tasks.
Journal ArticleDOI
Análise forense de documentos digitais: além da visão humana
Ewerton Silva,Anderson Rocha +1 more
TL;DR: The Digital Document Forensics research field is addressed, emphasizing ethical and legal implications of adulteration in digital images and some of the most interesting cases of forgery in different contexts such as in politics, scientific research and Forensic Medicine are presented.
Journal ArticleDOI
A Change-Driven Image Foveation Approach for Tracking Plant Phenology
Ewerton Silva,Ricardo da Silva Torres,Bruna Alberton,Leonor Patrícia Cerdeira Morellato,Thiago Sanna Freire Silva +4 more
TL;DR: This paper proposes an image foveation approach towards plant phenology tracking where relevant changes within an image time series guide the creation of foveal models used to resample unseen images.
