Audio-Text Cross-Attention with Psycholinguistic Support Features for Ambivalence/Hesitancy Recognition
Luiz F. B. F. Martins, Rodrigo W. Pisaia, Matheus M. Girardi +5
The paper proposes a multimodal system that combines audio prosodic descriptors, RoBERTa text embeddings, and handcrafted psycholinguistic features via cross‑attention and multiple…
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…
Computer Vision for MOBA Analytics: A Dataset and Baseline for Visibility Analysis in Dota 2
Ricardo da Rocha Carvalho, EloÃsa Oliveira, Luiz Bernardo Martins Kummer +2
Introduction: Most Multiplayer Online Battle Arena (MOBA) analytics studies rely on structured data, which does not directly capture what each team could actually see during a matc…
Toward Parking Spot Occupancy Recognition: A Self-Supervised Approach
Luan Marko Kujavski, Rayson Laroca, Paulo Lisboa de Almeida
As urban areas expand, automatic monitoring of parking lots becomes essential for efficient and sustainable cities. This work proposes a self-supervised approach for parking spot o…
Revisiting Vehicle Color Recognition in Long-Tailed Surveillance Scenarios
VinÃcius Orrú, Bruno H. Foggiatto, Gabriel E. Lima +2
Vehicle color recognition is an important cue for vehicle identification in surveillance systems, especially when license plates are illegible due to low resolution, occlusion, mot…
CEZSAR: A Contrastive Embedding Method for Zero-Shot Action Recognition
Valter Estevam, Rayson Laroca, Helio Pedrini +1
This paper proposes a novel Zero-Shot Action Recognition~(ZSAR) method based on contrastive learning. In ZSAR, we aim to classify examples from classes that were missing during tra…
