Cross-Correlation Template Matching For Liver Localisation In Computed Tomography, Patrick Leyden, Martin O'Connell, Derek Greene, Kathleen Curran Jan 2019

Cross-Correlation Template Matching For Liver Localisation In Computed Tomography, Patrick Leyden, Martin O'Connell, Derek Greene, Kathleen Curran

Session 5: Medical and Biomedical Imaging

Many of the current approaches to automatic organ localisation in medical imaging require a large amount of labelled patient data to train systems to accurately identify specific anatomical features. Cross- Correlation, also known as template matching, is a statistical method of assessing the similarity between a template image and a target image. This method has been modified and presented here to localize the liver in Computed Tomography volume images in the Coronal and Sagital planes to achieve a mean positioning error of approximately 11 mm and 20 mm respectively based on between 1 and 25 datasets to create the template …


Tracking Hand Trajectory As A Preliminary Study For Hand Hygiene Stages, Rashmi Bakshi, Jane Courtney, Damon Berry, Graham Gavin Jan 2019

Tracking Hand Trajectory As A Preliminary Study For Hand Hygiene Stages, Rashmi Bakshi, Jane Courtney, Damon Berry, Graham Gavin

Session 5: Medical and Biomedical Imaging

The process of hand washing involves complex hand movements. There are six principal sequential steps for washing hands as per the World Health Organisation (WHO) guidelines. In this work, a preliminary analysis was undertaken in order to develop an automated image processing system for tracking and classification of two-handed dynamic gestures involved in hand washing. To facilitate this study, videos of healthcare workers who were engaged in washing hands were sourced from the internet. The videos were analysed in order to extract the unique features of two-handed gestures associated with all hand hygiene (HH) stages. The combination of these unique …


Eulerian Video Magnification Adaptation For Live Cell Microscopy Analysis, Paul Leamy, Jane Courtney Jan 2019

Eulerian Video Magnification Adaptation For Live Cell Microscopy Analysis, Paul Leamy, Jane Courtney

Session 5: Medical and Biomedical Imaging

In this paper an adaptation of the Eulerian Video Magnification technique is described for use with .TIFF files produced by a photo-conversion time lapse protocol for live cell microscopy, specifically for research into Acquired Immune Deficiency Syndrome. The tracking and characterisation of a protein found in Human Immunodeficiency Virus, to determine its dynamics and pathways is a key determinant in understanding the protein’s function. The aim of this algorithm is to process an image sequence in the temporal direction with the result being that changes in fluorescence for particular pixel locations, or regions of interest, are tracked and filtered thereby …
