Automatic Segmentation and Inpainting of Specular Highlights for Endoscopic Imaging
Lacey, Gerard (2010)Minimally invasive medical procedures have become increasingly common in today's healthcare practice. Images taken during such procedures largely show tissues of human organs, such as the mucosa of the gastrointestinal ... -
The Design and Implementation of Lego Volleyball Robots.
Lacey, Gerard; Cassidy, Derek (Trinity College Dublin, 1999)The aim of the LEGO robot project was to develop a team of robots to compete in a scaled down version of volleyball. The competition was held in Sheffield, as part of the British Association for Science Annual exhibition, ... -
Efficacy of a new educational tool to improve Handrubbing technique amongst healthcare workers: a controlled, before-after study.
Lacey, Gerard (2014)Introduction: Hand hygiene is a key component of infection control in healthcare. WHO recommends that healthcare workers perform six specific poses during each hand hygiene action. SureWash (Glanta Ltd, Dublin, Ireland) ... -
Experts vs. novices: applying eye-tracking methodologies in colonoscopy video screening for polyp search
Lacey, Gerard; Bernal, Jorge; Sánchez, Javier; Vilariño, Fernando; Arnold, Mirko; Ghosh, Anarta (ACM, 2014)We present in this paper a novel study aiming at identifying the differences in visual search patterns between physicians of diverse levels of expertise during the screening of colonoscopy videos. Physicians were clustered ... -
Eye-tracking for efficient database labelling: Applications to automatic analysis of colonoscopy video
Lacey, Gerard; Vilarino, Fernando (2007)In this paper we present our preliminary results in the automatic analysis of colonoscopy video using eye-tracking. We propose that eye-tracking can be successfully applied to solve different problems in computer assisted ... -

Measuring surgical knot tying with 3D vision and VR gloves
Lacey, Gerard; Ridgway, Paul; Bhattacharya, Jhilik (2019)One handed surgical knot tying is one of the core skills of surgeons. The development of this skill takes time and one-on-one expert supervision. Our motivation is to provide good quality automatic evaluation in order ... -
Method and system for recovery of 3D scene structure and camera motion from a video sequence
Lacey, Gerard; Yous, Sofiane; Redmond, Peter (USPTOUSPTO, 2015)An improved method and a system are disclosed for recovering a three-dimensional (3D) scene structure from a plurality of two-dimensional (2D) image frames obtained from imaging means. Sets of 2D features are extracted ... -
A multi-class SVM classifier ensemble for automatic hand washing quality assessment
Lacey, Gerard; LLorca, D.F.; Vilarino, F.; Zhou, Z. (2007)Hand washing is a critical activity in preventing the spread of infection in health-care environments. Several guidelines recommended a hand washing protocol consisting of six steps that ensure that all areas of the hands ... -
Recognising Actions for Instructional Training using Pose Information: A Comparative Evaluation.
Lacey, Gerard (2019)Humans perform many complex tasks involving the manipulation of multiple objects. Recognition of the constituent actions of these tasks can be used to drive instructional training systems. The identities and poses of the ... -
Restoration of colour channel misalignments in colonoscopy videos
Lacey, Gerard; Dahoyt, Rozenn (Trinity College Dublin, 2007)We propose a method to restore colonoscopy videos that have low quality RGB images. The main problem concerns a time delay occurring in between the recordings of the R, G and B colour channels. As the camera is moving ... -
