Synthesizing Traffic Datasets using Graph Neural Networks

1 code implementation8 Dec 2023 Daniel Rodriguez-Criado, Maria Chli, Luis J. Manso, George Vogiatzis

This paper introduces a novel methodology for bridging this `sim-real' gap by creating photorealistic images from 2D traffic simulations and recorded junction footage.

Self-supervised Monocular Depth Estimation: Let's Talk About The Weather

1 code implementation ICCV 2023 Kieran Saunders, George Vogiatzis, Luis Manso

For these architectures to be effective in real-world applications, we must create models that can generalise to all weather conditions, times of the day and image qualities.

Multi-camera Torso Pose Estimation using Graph Neural Networks

1 code implementation28 Jul 2020 Daniel Rodriguez-Criado, Pilar Bachiller, Pablo Bustos, George Vogiatzis, Luis J. Manso

The proposal presented in this paper makes use of graph neural networks to merge the information acquired from multiple camera sources, achieving a mean absolute error below 125 mm for the location and 10 degrees for the orientation using low-resolution RGB images.

Look and Listen: A Multi-modality Late Fusion Approach to Scene Classification for Autonomous Machines

no code implementations11 Jul 2020 Jordan J. Bird, Diego R. Faria, Cristiano Premebida, Anikó Ekárt, George Vogiatzis

The image and the audio datasets are first classified independently, using a fine-tuned VGG16 and an evolutionary optimised deep neural network, with accuracies of 89. 27% and 93. 72%, respectively.

Domain Adaptation for Reinforcement Learning on the Atari

no code implementations18 Dec 2018 Thomas Carr, Maria Chli, George Vogiatzis

Deep reinforcement learning agents have recently been successful across a variety of discrete and continuous control tasks; however, they can be slow to train and require a large number of interactions with the environment to learn a suitable policy.

Learning Non-Metric Visual Similarity for Image Retrieval

no code implementations ICLR 2018 Noa Garcia, George Vogiatzis

Theoretically, non-metric distances are able to generate a more complex and accurate similarity model than metric distances, provided that the non-linear data distribution is precisely captured by the system.

Large Scale Multi-view Stereopsis Evaluation

no code implementations CVPR 2014 Rasmus Jensen, Anders Dahl, George Vogiatzis, Engin Tola, Henrik Aanaes

The seminal multiple view stereo benchmark evaluations from Middlebury and by Strecha et al. have played a major role in propelling the development of multi-view stereopsis methodology.
