Human Scanpath Prediction in Target-Present Visual Search with Semantic-Foveal Bayesian Attention
João Luzio, Alexandre Bernardino, Plinio Moreno
In goal-directed visual tasks, human perception is guided by both top-down and bottom-up cues. At the same time, foveal vision plays a crucial role in directing attention efficient…
Next Best View For Point-Cloud Model Acquisition: Bayesian Approximation and Uncertainty Analysis
Madalena Caldeira, Plinio Moreno
The Next Best View problem is a computer vision problem widely studied in robotics. To solve it, several methodologies have been proposed over the years. Some, more recently, propo…
Semantic-Based Active Perception for Humanoid Visual Tasks with Foveal Sensors
João Luzio, Alexandre Bernardino, Plinio Moreno
The aim of this work is to establish how accurately a recent semantic-based foveal active perception model is able to complete visual tasks that are regularly performed by humans,…
Action-conditioned Benchmarking of Robotic Video Prediction Models: a Comparative Study
Manuel Serra Nunes, Atabak Dehban, Plinio Moreno +1
A defining characteristic of intelligent systems is the ability to make action decisions based on the anticipated outcomes. Video prediction systems have been demonstrated as a sol…
Applying Domain Randomization to Synthetic Data for Object Category Detection
João Borrego, Atabak Dehban, Rui Figueiredo +3
Recent advances in deep learning-based object detection techniques have revolutionized their applicability in several fields. However, since these methods rely on unwieldy and larg…
