Cost-Efficient Multi-Scale Fovea for Semantic-Based Visual Search Attention
João Luzio, Alexandre Bernardino, Plinio Moreno
Semantics are one of the primary sources of top-down preattentive information. Modern deep object detectors excel at extracting such valuable semantic cues from complex visual scen…
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…
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,…
Pose-free object classification from surface contact features in sequences of Robotic grasps
Teresa Alves, Alexandre Bernardino, Plinio Moreno
In this work, we propose two cost efficient methods for object identification, using a multi-fingered robotic hand equipped with proprioceptive sensing. Both methods are trained on…
