Résumé

Bio

Postdoctoral Researcher at Istituto Italiano di Tecnologia (IIT) working on 3D scene understanding with Dr Alessio Del Bue. Previously Stuart was a currently a Research Associate at University College London (UCL). At UCL Stuart's research focused on cultural heritage domain including fine-detail 3D reconstruction of large bas-relief art work belonging to the British Museum. In additional looking at the British Library book illustration dataset, creating algorithms for segmentation of cross-hatch imagery. Previous to his time at UCL, Stuart completed a post-doc at University of Surrey looking at social media implications across different lifespan transitions; utilising multi-label classification and clustering through Deep Learning methods. Also at the University of Surrey, Stuart completed his PhD which explored how free-hand sketched storyboards can be used for retrieval and synthesis of video. Developing novel algorithms for video understanding and representation. Throughout his research career he has maintained a strong software engineering ethic and demonstrated this through prototype research systems.

Employment History

  • 2015

    Research Associate Oct 2015 - Marcch 2017

    University College London London, UK

    Working under Prof. Tim Weyrich

    This project explores two different aspects of Digital Heritage analysis of artefacts and printed illustrations. Firstly the 3D reconstruction of artefacts, specifical bas-relief, provides challenges to traditionally computer vision methods. By utilising and developing new combinations of multiview photometric stereo and structure from motion we aim to reconstruct British Museum assets. Secondly exploring the analysis of illustrations of historical books provided by the British Library we develop an approach to segment sparse line structures with learnt shading styles.

    Research Fellow Aug 2013 - Sept 2015

    University of Surrey Guildford, UK

    Working under Dr John Collomosse

    An EPSRC funded project exploring the digital effect on key life transition points, through Social Media. The project required the development of algorithms for classification and clustering utilising both Image and Text. Additional explored data purification of large noisy social media datasets using Genetic Algorithms. As well as a structured manifold mapping techniques for presentation of user data through a 2D game interface.

    PhD Visual Information Retrieval March 2015 Guildford, UK

    Visual Narratives Free-hand Sketch for Visual Search and Navigation of Video

    Media retrieval has been dominated by text-based queries utilising meta-data tags, but such queries are cumbersome to describe the appearance and in the case of video temporal information. We propose methods using sketch as an intuitive way to describe and search such media content. Sketch based Video retrieval has traditionally applied complex model fitting, in contrast, we explore representations suitable for index structure to achieve sublinear query time. Which also makes it possible to get the user in the loop through relevance feedback. Secondly, we propose Sketch based Human Pose Retrieval (SBHPR), a method of finding humans postures within videos using stickman depictions. Developing a manifold based retrieval method and learning a domain adaptation to improve precision on new videos. Finally, we extended the SBHPR method to a storyboard allowing a sequence of pose and action labels (run, jump) to be intertwined. This is demonstrated for video segment retrieval and synthesis of a new video, by extending the motion graph technique.
