Attention-based fusion of semantic boundary and non-boundary information to improve semantic segmentation
Jefferson Fontinele, Gabriel Lefundes, Luciano Oliveira
This paper introduces a method for image semantic segmentation grounded on a novel fusion scheme, which takes place inside a deep convolutional neural network. The main goal of our…
On estimating gaze by self-attention augmented convolutions
Gabriel Lefundes, Luciano Oliveira
Estimation of 3D gaze is highly relevant to multiple fields, including but not limited to interactive systems, specialized human-computer interfaces, and behavioral research. Altho…
Rotation-invariant shipwreck recognition with forward-looking sonar
Gustavo Neves, Rômulo Cerqueira, Jan Albiez +1
Under the sea, visible spectrum cameras have limited sensing capacity, being able to detect objects only in clear water, but in a constrained range. Considering any sea water condi…
ISEC: Iterative over-Segmentation via Edge Clustering
Marcelo Santos, Luciano Oliveira
Several image pattern recognition tasks rely on superpixel generation as a fundamental step. Image analysis based on superpixels facilitates domain-specific applications, also spee…
Automatic segmenting teeth in X-ray images: Trends, a novel data set, benchmarking and future perspectives
Gil Jader, Luciano Oliveira, Matheus Pithon
This review presents an in-depth study of the literature on segmentation methods applied in dental imaging. Ten segmentation methods were studied and categorized according to the t…
How far did we get in face spoofing detection?
Luiz Souza, Mauricio Pamplona, Luciano Oliveira +1
The growing use of control access systems based on face recognition shed light over the need for even more accurate systems to detect face spoofing attacks. In this paper, an exten…
