Scalable and Efficient Hierarchical Visual Topological Mapping

1 code implementation7 Apr 2024 Saravanabalagi Ramachandran, Jonathan Horgan, Ganesh Sistu, John McDonald

Based on our empirical analysis of multiple runs, we identify that continuity and distinctiveness are crucial characteristics for an optimal global descriptor that enable efficient and scalable hierarchical mapping, and present a methodology for quantifying and contrasting these characteristics across different global descriptors.

Surround-View Fisheye Optics in Computer Vision and Simulation: Survey and Challenges

no code implementations19 Feb 2024 Daniel Jakab, Brian Michael Deegan, Sushil Sharma, Eoin Martino Grua, Jonathan Horgan, Enda Ward, Pepijn Van de Ven, Anthony Scanlan, Ciarán Eising

Overall, this paper highlights the optical aberrations in automotive fisheye datasets, and the limitations of optical reality in simulated fisheye datasets, with a focus on computer vision in surround-view optical systems.

Revisiting Modality Imbalance In Multimodal Pedestrian Detection

no code implementations24 Feb 2023 Arindam Das, Sudip Das, Ganesh Sistu, Jonathan Horgan, Ujjwal Bhattacharya, Edward Jones, Martin Glavin, Ciarán Eising

Multimodal learning, particularly for pedestrian detection, has recently received emphasis due to its capability to function equally well in several critical autonomous driving scenarios such as low-light, night-time, and adverse weather conditions.

Fast and Efficient Scene Categorization for Autonomous Driving using VAEs

no code implementations26 Oct 2022 Saravanabalagi Ramachandran, Jonathan Horgan, Ganesh Sistu, John McDonald

We train a Variational Autoencoder in an unsupervised manner and map images to a constrained multi-dimensional latent space and use the latent vectors as compact embeddings that serve as global descriptors for images.

2.5D Vehicle Odometry Estimation

no code implementations16 Nov 2021 Ciaran Eising, Leroy-Francisco Pereira, Jonathan Horgan, Anbuchezhiyan Selvaraju, John McDonald, Paul Moran

We show, by experimental results with a DGPS/IMU reference, that this model provides highly accurate odometry estimates, compared with existing methods.

A 2.5D Vehicle Odometry Estimation for Vision Applications

no code implementations6 May 2021 Paul Moran, Leroy-Francisco Periera, Anbuchezhiyan Selvaraju, Tejash Prakash, Pantelis Ermilios, John McDonald, Jonathan Horgan, Ciarán Eising

This paper proposes a method to estimate the pose of a sensor mounted on a vehicle as the vehicle moves through the world, an important topic for autonomous driving systems.

Near-field Perception for Low-Speed Vehicle Automation using Surround-view Fisheye Cameras

no code implementations31 Mar 2021 Ciaran Eising, Jonathan Horgan, Senthil Yogamani

In this work, we provide a detailed survey of such vision systems, setting up the survey in the context of an architecture that can be decomposed into four modular components namely Recognition, Reconstruction, Relocalization, and Reorganization.
