Evolutionary Data Purification for Social Media Classification (2016)
Presentation / Conference Contribution
James, S., & Collomosse, J. (2016, December). Evolutionary Data Purification for Social Media Classification. Presented at 2016 23rd International Conference on Pattern Recognition (ICPR), Cancun, Mexico

We present a novel algorithm for the semantic labeling of photographs shared via social media. Such imagery is diverse, exhibiting high intra-class variation that demands large training data volumes to learn representative classifiers. Unfortunately...

A Particle Filtering approach to salient video object localization (2014)
Presentation / Conference Contribution
Gray, C., James, S., Collomosse, J., & Asente, P. (2014, October). A Particle Filtering approach to salient video object localization. Presented at 2014 IEEE International Conference on Image Processing (ICIP), Paris, France

We describe a novel fully automatic algorithm for identifying salient objects in video based on their motion. Spatially coherent clusters of optical flow vectors are sampled to generate estimates of affine motion parameters local to super-pixels iden...

Enhanced Digital Literacy by Multi-modal Data Mining of the Digital Lifespan (2014)
Presentation / Conference Contribution
Collomosse, J., James, S., Durrant, A., Trujillo-Pisanty, D., Moncur, W., Orzech, K. M., Martindale, S., & Chantler, M. (2014, December). Enhanced Digital Literacy by Multi-modal Data Mining of the Digital Lifespan. Presented at Fifth Annual Digital Economy All Hands Meeting, London

Social media pervades modern digital society, yet despite its regular use the general level of digital literacy and awareness of online representations of self remain low. We report progress on the RCUK DE funded ‘Charting the Digital Lifespan’ proje... Read More about Enhanced Digital Literacy by Multi-modal Data Mining of the Digital Lifespan.

Interactive Video Asset Retrieval Using Sketched Queries (2014)
Presentation / Conference Contribution
James, S., & Collomosse, J. (2014, November). Interactive Video Asset Retrieval Using Sketched Queries. Presented at CVMP '14: 11th European Conference on Visual Media Production, London

We present a new algorithm for searching video repositories using free-hand sketches. Our queries express both appearance (color, shape) and motion attributes, as well as semantic properties (object labels) enabling hybrid queries to be specified. Un...

Admixed Portrait: Design Intervention to Prompt Reflection on Being Online as a New Parent (2014)
Presentation / Conference Contribution
Trujillo-Pisanty, D., Durrant, A., Martindale, S., James, S., & Collomosse, J. (2014, June). Admixed Portrait: Design Intervention to Prompt Reflection on Being Online as a New Parent. Presented at DIS '14: 2014 conference on Designing interactive systems, Vancouver, BC, Canada

This Pictorial documents the process of designing a device as an intervention within a field study of new parents. The device was deployed in participating parents' homes to invite reflection on their everyday experiences of portraying self and other...

ReEnact: Sketch Based Choreographic Design from Archival Dance Footage (2014)
Presentation / Conference Contribution
James, S., Fonseca, M. J., & Collomosse, J. (2014, April). ReEnact: Sketch Based Choreographic Design from Archival Dance Footage. Presented at ICMR '14: International Conference on Multimedia Retrieval, Glasgow

We describe a novel system for synthesising video choreography using sketched visual storyboards comprising human poses (stick men) and action labels. First, we describe an algorithm for searching archival dance footage using sketched pose. We match... Read More about ReEnact: Sketch Based Choreographic Design from Archival Dance Footage.

Implicit surface reconstruction and feature detection with a learning algorithm (2010)
Presentation / Conference Contribution
Kaye, D., & Ivrissimtzis, I. (2010, September). Implicit surface reconstruction and feature detection with a learning algorithm. Presented at Theory and Practice of Computer Graphics, Sheffield, UK

We propose a new algorithm for implicit surface reconstruction and feature detection. The algorithm is based on a self organising map with the connectivity of a regular 3D grid that can be trained into an implicit representation of surface data. The...
