Large-scale fully-unsupervised re-identification
Fully-unsupervised Person and Vehicle Re-Identification have received increasing attention due to their broad applicability in surveillance, forensics, event understanding, and …
The Age of Synthetic Realities: Challenges and Opportunities
Synthetic realities are digital creations or augmentations that are contextually generated through the use of Artificial Intelligence (AI) methods, leveraging extensive amounts of …
Leveraging Ensembles and Self-Supervised Learning for Fully-Unsupervised Person Re-Identification and Text Authorship Attribution
Self-supervised learning deals with problems that have little or no available labeled data. Recent work has shown impressive results when underlying classes have significant …
Unsupervised and self-adaptative techniques for cross-domain person re-identification
Person Re-Identification (ReID) across non-overlapping cameras is a challenging task and, for this reason, most works in the prior art rely on supervised feature learning from a …
Content-Based Detection of Temporal Metadata Manipulation
Most pictures shared online are accompanied by a temporal context (i.e., the moment they were taken) that aids their understanding and the history behind them. Claiming that these …
Automatic reconstruction of ancient Portuguese tile panels
Portuguese tile panels, or azulejos, are one of Portugal’s cultural icons, and a representative cultural heritage of this country. Portugal’s museums currently have a large …
A Graph Cut approach to texture synthesis on 3D surfaces
We present a novel method for synthesizing texture over a 3D model from 2D photographs of the modeled object. By considering an optimization approach, we subdivide the mesh into …
