Unsupervised Class Generation to Expand Semantic Segmentation Datasets

no code implementations4 Jan 2025 Javier Montalvo, Álvaro García-Martín, Pablo Carballeira, Juan C. SanMiguel

To mitigate this cost there has been a surge in the use of synthetically generated data -- usually created using simulators or videogames -- which, in combination with domain adaptation methods, can effectively learn how to segment real data.

Leveraging Contrastive Learning for Semantic Segmentation with Consistent Labels Across Varying Appearances

no code implementations21 Dec 2024 Javier Montalvo, Roberto Alcover-Couso, Pablo Carballeira, Álvaro García-Martín, Juan C. SanMiguel, Marcos Escudero-Viñolo

This paper introduces a novel synthetic dataset that captures urban scenes under a variety of weather conditions, providing pixel-perfect, ground-truth-aligned images to facilitate effective feature alignment across domains.

Test-Time Adaptation for Keypoint-Based Spacecraft Pose Estimation Based on Predicted-View Synthesis

1 code implementation5 Oct 2024 Juan Ignacio Bravo Pérez-Villar, Álvaro García-Martín, Jesús Bescós, Juan C. SanMiguel

Due to the difficulty of replicating the real conditions during training, supervised algorithms for spacecraft pose estimation experience a drop in performance when trained on synthetic data and applied to real operational data.

Gradient-based Class Weighting for Unsupervised Domain Adaptation in Dense Prediction Visual Tasks

no code implementations1 Jul 2024 Roberto Alcover-Couso, Marcos Escudero-Viñolo, Juan C. SanMiguel, Jesus Bescós

In unsupervised domain adaptation (UDA), where models are trained on source data (e. g., synthetic) and adapted to target data (e. g., real-world) without target annotations, addressing the challenge of significant class imbalance remains an open issue.

Detection-aware multi-object tracking evaluation

no code implementations16 Dec 2022 Juan C. SanMiguel, Jorge Muñoz, Fabio Poiesi

How would you fairly evaluate two multi-object tracking algorithms (i. e. trackers), each one employing a different object detector?

Attention-based Knowledge Distillation in Multi-attention Tasks: The Impact of a DCT-driven Loss

no code implementations4 May 2022 Alejandro López-Cifuentes, Marcos Escudero-Viñolo, Jesús Bescós, Juan C. SanMiguel

Feature-based Knowledge Distillation is a subfield of KD that relies on intermediate network representations, either unaltered or depth-reduced via maximum activation maps, as the source knowledge.

Graph Neural Networks for Cross-Camera Data Association

2 code implementations17 Jan 2022 Elena Luna, Juan C. SanMiguel, José M. Martínez, Pablo Carballeira

To avoid the usage of fixed distances, we leverage the connectivity of Graph Neural Networks, previously unused in this scope, using a Message Passing Network to jointly learn features and similarity.

On guiding video object segmentation

no code implementations25 Apr 2019 Diego Ortego, Kevin McGuinness, Juan C. SanMiguel, Eric Arazo, José M. Martínez, Noel E. O'Connor

This guiding process relies on foreground masks from independent algorithms (i. e. state-of-the-art algorithms) to implement an attention mechanism that incorporates the spatial location of foreground and background to compute their separated representations.
