A Semi-supervised Object Detection Algorithm for Underwater Imagery
Suraj Bijjahalli, Oscar Pizarro, Stefan B. Williams
Detection of artificial objects from underwater imagery gathered by Autonomous Underwater Vehicles (AUVs) is a key requirement for many subsea applications. Real-world AUV image da…
Improved Benthic Classification using Resolution Scaling and SymmNet Unsupervised Domain Adaptation
Heather Doig, Oscar Pizarro, Stefan B. Williams
Autonomous Underwater Vehicles (AUVs) conduct regular visual surveys of marine environments to characterise and monitor the composition and diversity of the benthos. The use of mac…
Maximising Wrenches for Kinematically Redundant Systems with Experiments on UVMS
Wilhelm Johan Marais, Stefan B. Williams, Oscar Pizarro
This paper presents methods for finding optimal configurations and actuator forces/torques to maximise contact wrenches in a desired direction for Underwater Vehicles Manipulator S…
Towards Automated Sample Collection and Return in Extreme Underwater Environments
Gideon Billings, Matthew Walter, Oscar Pizarro +2
In this report, we present the system design, operational strategy, and results of coordinated multi-vehicle field demonstrations of autonomous marine robotic technologies in searc…
GeoCLR: Georeference Contrastive Learning for Efficient Seafloor Image Interpretation
Takaki Yamada, Adam Prügel-Bennett, Stefan B. Williams +2
This paper describes Georeference Contrastive Learning of visual Representation (GeoCLR) for efficient training of deep-learning Convolutional Neural Networks (CNNs). The method le…
Field trial on Ocean Estimation for Multi-Vessel Multi-Float-based Active perception
Giovanni D'urso, James Ju Heon Lee, Ki Myung Brian Lee +5
Marine vehicles have been used for various scientific missions where information over features of interest is collected. In order to maximise efficiency in collecting information o…
Feature Space Exploration For Planning Initial Benthic AUV Surveys
Jackson Shields, Oscar Pizarro, Stefan B. Williams
Special-purpose Autonomous Underwater Vehicles (AUVs) are utilised for benthic (seafloor) surveys, where the vehicle collects optical imagery of the seafloor. Due to the small-sens…
Towards Adaptive Benthic Habitat Mapping
Jackson Shields, Oscar Pizarro, Stefan B. Williams
Autonomous Underwater Vehicles (AUVs) are increasingly being used to support scientific research and monitoring studies. One such application is in benthic habitat mapping where th…
