Reliable Geofence Activation with Sparse and Sporadic Location Measurements: Extended Version

no code implementations1 Apr 2022 Kien Nguyen, John Krumm

Complicating this prediction approach is the fact that another location measurement could appear at any time, making the prediction redundant and wasteful.

The State of Aerial Surveillance: A Survey

no code implementations9 Jan 2022 Kien Nguyen, Clinton Fookes, Sridha Sridharan, YingLi Tian, Feng Liu, Xiaoming Liu, Arun Ross

The rapid emergence of airborne platforms and imaging sensors are enabling new forms of aerial surveillance due to their unprecedented advantages in scale, mobility, deployment and covert observation capabilities.

Gaussian Process for Trajectories

no code implementations7 Oct 2021 Kien Nguyen, John Krumm, Cyrus Shahabi

The Gaussian process is a powerful and flexible technique for interpolating spatiotemporal data, especially with its ability to capture complex trends and uncertainty from the input signal.

In Defense of Scene Graphs for Image Captioning

1 code implementation ICCV 2021 Kien Nguyen, Subarna Tripathi, Bang Du, Tanaya Guha, Truong Q. Nguyen

Several studies have noted that the naive use of scene graphs from a black-box scene graph generator harms image captioning performance and that scene graph-based captioning models have to incur the overhead of explicit use of image features to generate decent captions.

Complex-valued Iris Recognition Network

no code implementations23 Nov 2020 Kien Nguyen, Clinton Fookes, Sridha Sridharan, Arun Ross

Unlike the problem of general object recognition, where real-valued neural networks can be used to extract pertinent features, iris recognition depends on the extraction of both phase and magnitude information from the input iris texture in order to better represent its biometric content.

Spatial Privacy Pricing: The Interplay between Privacy, Utility and Price in Geo-Marketplaces

no code implementations25 Aug 2020 Kien Nguyen, John Krumm, Cyrus Shahabi

Users concerned about privacy may want to charge more for data that pinpoints their location accurately, but may charge less for data that is more vague.

Constrained Design of Deep Iris Networks

no code implementations23 May 2019 Kien Nguyen, Clinton Fookes, Sridha Sridharan

On the other hand, it allows us to investigate the optimality of the classic IrisCode and recent iris networks.

Sparse Over-complete Patch Matching

no code implementations9 Jun 2018 Akila Pemasiri, Kien Nguyen, Sridha Sridharan, Clinton Fookes

State -of-the-art patch matching techniques take image patches as input to a convolutional neural network to extract the patch features and evaluate their similarity.

Meta Transfer Learning for Facial Emotion Recognition

no code implementations25 May 2018 Dung Nguyen, Kien Nguyen, Sridha Sridharan, Iman Abbasnejad, David Dean, Clinton Fookes

The use of deep learning techniques for automatic facial expression recognition has recently attracted great interest but developed models are still unable to generalize well due to the lack of large emotion datasets for deep learning.
