VeriCam: A Verification Baseline for the Classification of Unknown Data
Lucas Wojcik, Gabriel E. Lima, Sergio M. Silva +2
The advent of foundation models have enabled a new era in zero-shot classification. Yet, key challenges persist. Despite their impressive generalization power that leverages the im…
A Benchmark for Vehicle Attribute Classification in Cross-Domain Surveillance Scenarios
Sergio M. Silva, Otavio T. Remer, Gabriel E. Lima +3
Vehicle attribute analysis is a key component of Intelligent Transportation Systems (ITS), supporting applications such as vehicle identification, traffic monitoring, and forensic…
Identity-Conditioned Latent Consistency Distillation for Face Synthesis
Tiago Kienen Chaves, Bernardo Biesseck, David Menotti
Diffusion models have achieved strong results in high-fidelity image synthesis, but their iterative sampling process makes large-scale generation computationally expensive. This li…
UFPR-PEs: A Brazilian Face Recognition Benchmark with Self-Declared Race/Color Labels
Alexandre Diano, Bernardo Biesseck, Gabriel Polo +4
While face recognition systems are widely deployed, ensuring their demographic reliability and robustness under uncontrolled visual conditions remains a critical challenge. To brid…
Evaluating 2D and 3D-Aware Vision Foundation Models for Vehicle Attribute Recognition
Alexandre V. Delazeri, Gabriel E. Lima, Eduil Nascimento +2
Vehicle attribute recognition is an important task in intelligent transportation systems, particularly when Automatic License Plate Recognition (ALPR) is unavailable or unreliable.…
Robust Face Super-Resolution and Recognition Through Multi-Feature Aggregation in Diffusion Models
Marcelo dos Santos, Rayson Laroca, João Carlos Raposo Neves +1
Images acquired in surveillance environments often suffer from conditions such as low resolution, variations in pose, irregular illumination, and occlusions. Due to the low quality…
