Shape-constrained and unconstrained density estimation using geometric exploration (2018)
Presentation / Conference Contribution
The problem of nonparametrically estimating probability density functions (pdfs) from observed data requires posing and solving optimization problems on the space of pdfs. We take a geometric approach and explore this space for optimization using act... Read More about Shape-constrained and unconstrained density estimation using geometric exploration.
A conceptual framework for social movements analytics for national security (2018)
Presentation / Conference Contribution
Social media tools have changed our world due to the way they convey information between individuals; this has led to many social movements either starting on social media or being organised and managed through this medium. At times however, certain... Read More about A conceptual framework for social movements analytics for national security.
Temporal Graph Offset Reconstruction: Towards Temporally Robust Graph Representation Learning (2018)
Presentation / Conference Contribution
Graphs are a commonly used construct for representing relationships between elements in complex high dimensional datasets. Many real-world phenomenon are dynamic in nature, meaning that any graph used to represent them is inherently temporal. However...

Closed loop adaptive optics with a laser guide star for biological light microscopy (2012)
Presentation / Conference Contribution
We report on the development of a widefield microscope that achieves adaptive optics correction through the use of a wavefront sensor observing an artificial laser guide star induced within the sample. By generating this guide star at arbitrary posit... Read More about Closed loop adaptive optics with a laser guide star for biological light microscopy.
Elastic 3D shape analysis using square-root normal field representation (2017)
Presentation / Conference Contribution
Shape is an important physical property of natural and man-made 3D objects that characterizes their external appearances. Understanding differences between shapes, and modeling the variability within and across shape classes, hereinafter referred to...

Realtime wavefront sensing in a SPIM microscope, and active aberration tracking (2015)
Presentation / Conference Contribution
Adaptive optics (AO) can potentially allow high resolution imaging deep inside living tissue, mitigating against the loss of resolution due to aberrations caused by overlying tissue. Closed-loop AO correction is particularly attractive for moving tis... Read More about Realtime wavefront sensing in a SPIM microscope, and active aberration tracking.
Evaluating the quality of graph embeddings via topological feature reconstruction (2017)
Presentation / Conference Contribution
Adaptive optics for wide-field microscopy (2011)
Presentation / Conference Contribution
We report on recent developments in the use of adaptive optics (AO) in wide-field microscopy to remove both system and sample induced aberrations. We describe progress on using both a full AO system and image optimization techniques (wavefront sensor... Read More about Adaptive optics for wide-field microscopy.
Avoiding over-detection: towards combined object detection and counting (2017)
Presentation / Conference Contribution
Existing object detection frameworks in the deep learning field generally over-detect objects, and use non-maximum suppression (NMS) to filter out excess detections, leaving one bounding box per object. This works well so long as the ground-truth bou... Read More about Avoiding over-detection: towards combined object detection and counting.
Contrast-independent curvilinear structure enhancement in 3D biomedical images (2017)
Presentation / Conference Contribution
A wide range of biomedical applications require detection, quantification and modelling of curvilinear structures in 3D images. Here we propose a 3D contrast-independent approach to enhance curvilinear structures based on the 3D Phase Congruency Tens...

2D adaptive grid-based image analysis approach for biological networks (2016)
Presentation / Conference Contribution
The accurate analysis of biological networks, enabled by the precise capture of their individual components, can reveal important underlying biological principles. Efficient image processing techniques are required to precisely identify and quantify... Read More about 2D adaptive grid-based image analysis approach for biological networks.

Runway detection in high resolution remote sensing data (2015)
Presentation / Conference Contribution
Runways are vital descriptive features of airports and knowledge of their location is important to many aviation and military applications. With the recent wide availability of remote sensing data, there is demand for an automatic process of extracti... Read More about Runway detection in high resolution remote sensing data.

Elastic shape matching of parameterized surfaces using square root normal fields (2012)
Presentation / Conference Contribution
In this paper we define a new methodology for shape analysis of parameterized surfaces, where the main issues are: (1) choice of metric for shape comparisons and (2) invariance to reparameterization. We begin by defining a general elastic metric on t... Read More about Elastic shape matching of parameterized surfaces using square root normal fields.
