July 2016

We are a team of researchers, led by Dr. Xianghua Xie at the Department of Computer Science in Swansea University, working on both low level and high level Computer Vision problems and their applications to Medicine, Biology and Engineering. We have strong research interests in medical image analysis, image segmentation, image registration, 3D pose estimation and tracking, object recognition, real time processing, texture analysis, inspection, and machine learning. We are also expanding our research on big data and mining. We are welcoming talented, motivated people to join us to pursue research in the field of Computer Vision and Medical Image Understanding, and we are actively seeking collaborative opportunities across disciplines.

Dr. Xie is a CI on this project, which is a collaboration between Portsmouth Institute of Criminal Justice Studies and Swansea Computer Science. The project is concerned with the close integration of formal modelling, data mining, visual analytics and information security management in order to predict the impact of releasing public data sets that are essential to commercial functions and economy. Total FEC funding: £1.6M, 1 June 2016 - 30 November 2019. EP/N028139/1 (Swansea), EP/N027825/1 (Portsmouth).

Dec 2015 - We are pleased to announce that CONVERSE dataset is publicly available. CONVERSE is a human interaction recognition dataset intended for the exploration of classifying naturally executed conversational scenarios between a pair of individuals via the use of pose- and appearance-based features. A in-depth survey of the current state of publicly available datasets to the action recognition community highlights several key layers in human action, from single person actions to multi-person interactions. Current depth-based datasets describe actions or interactions in which classes are often represented by a series of key poses which are readily identified in depth-based representations (i.e. kicks and punches). The motivation behind CONVERSE is to present the problem of classifying subtle and complex behaviours between participants with pose-based information, classes which are not easily defined by the poses they contain.
