Well-being is a complex concept, that can be affected by long-term or temporary disabilities, as well as the natural process of aging. Nowadays, while meaningful computing methodologies have reached maturity, and a full awareness of the problem dimension has been reached, we are facing the objective of designing ad hoc technologies with the...

In this paper, a novel method for tracker fusion is proposed and evaluated for vision-based object tracking. This work combines three distinct popular techniques into a recursive Bayesian estimation algorithm. First, a semi-supervised learning approach is used to train deep neural networks capable of detecting anomalous visual tracking...

Effective assisted living environments must be able to infer how their occupants interact in a variety of scenarios. Gaze direction provides strong indications of how a person engages with the environment and its occupants. In this paper, we investigate the problem of gaze tracking in multi-camera assisted living environments. We propose a gaze...

Effective assisted living environments must be able to perform inferences on how their occupants interact with their environment. Gaze direction provides strong indications of how people interact with their surroundings. In this paper, we propose a gaze tracking method that uses a neural network regressor to estimate gazes from keypoints and...
