Domain Adaptation for Satellite-Borne Hyperspectral Cloud Detection

no code implementations5 Sep 2023 Andrew Du, Anh-Dzung Doan, Yee Wei Law, Tat-Jun Chin

However, prior to deployment, new missions that employ new sensors will not have enough representative datasets to train a CNN model, while a model trained solely on data from previous missions will underperform when deployed to process the data on the new missions.

Adversarial Attacks against a Satellite-borne Multispectral Cloud Detector

no code implementations3 Dec 2021 Andrew Du, Yee Wei Law, Michele Sasdelli, Bo Chen, Ken Clarke, Michael Brown, Tat-Jun Chin

In fact, advanced EO satellites perform deep learning-based cloud detection on board the satellites and downlink only clear-sky data to save precious bandwidth.

A Multi-viewpoint Outdoor Dataset for Human Action Recognition

1 code implementation7 Oct 2021 Asanka G. Perera, Yee Wei Law, Titilayo T. Ogunwa, Javaan Chahl

Owing to the articulated nature of the human body, it is challenging to detect an action from multiple viewpoints, particularly from an aerial viewpoint.

Physical Adversarial Attacks on an Aerial Imagery Object Detector

1 code implementation26 Aug 2021 Andrew Du, Bo Chen, Tat-Jun Chin, Yee Wei Law, Michele Sasdelli, Ramesh Rajasegaran, Dillon Campbell

In this work, we demonstrate one of the first efforts on physical adversarial attacks on aerial imagery, whereby adversarial patches were optimised, fabricated and installed on or near target objects (cars) to significantly reduce the efficacy of an object detector applied on overhead images.

UAV-GESTURE: A Dataset for UAV Control and Gesture Recognition

1 code implementation9 Jan 2019 Asanka G Perera, Yee Wei Law, Javaan Chahl

To fill this gap and enable research in wider application areas, we present a UAV gesture signals dataset recorded in an outdoor setting.
