DICTA 2017 - Keynote Speakers

Prof Graham Finlayson
University of East Anglia, United Kingdom

Biography: Graham Finlayson is a Professor of Computer Science at the University of East Anglia. He joined UEA in 1999 when he was awarded a full professorship at the age of 30. He was and remains the youngest ever professorial appointment at that institution. Graham trained in computer science first at the University of Strathclyde and then for his masters and doctoral degrees at Simon Fraser University where he was awarded a ‘Dean’s medal’ for the best PhD dissertation in his faculty. Prior to joining UEA, Graham was a lecturer at the University of York and then a founder and Reader at the Colour and Imaging Institute at the University of Derby. Professor Finlayson is interested in ‘Computing how we see’ and his research spans computer science (algorithms), engineering (embedded systems) and psychophysics (visual perception). He has published over 50 journal, over 200 referred conference papers and 25+ patents. He has won best paper prizes at several conferences including, “The 5th IS&T conference on Colour in Graphics, Imaging and Vision” (2010) and “the IEE conference on Visual Information Engineering” (1995). Many of Graham’s patents are implemented and used in commercial products including photo processing software, dedicated image processing hardware (ASICs) and in embedded camera software. Graham’s research is funded from a number of sources including government, industry and through investment for spin-out companies. Industrial partners include Apple, Hewlett Packard, Sony, Xerox, Unilever and Buhler-Sortex. Significantly, Graham was the first academic at UEA (in its 50 year history) to either raise venture capital investment for a spin-out company – Imsense Ltd developed technology to make pictures look better - or to make a money for the university when this company was subsequently sold to a blue chip industry major in 2010. In 2002, Graham was awarded the Philip Leverhulme prize for science and in 2008 a Royal Society-Wolfson Merit award. In 2009 the Royal Photographic Society presented graham with the Davies medal in recognition of his contributions to the Photographic Industry. The RPS made Graham a fellow in 2012. In recognition of distinguished service to the Society for Imaging Science and Technology, Graham was elected a fellow of that society in 2010. In January 2013 Graham was also elected to a fellowship of the Institute of Engineering Technology.

Title: Color Homography

Abstract: Images of co-planar points in 3-dimensional space taken from different camera positions are a homography apart. Homographies are at the heart of geometric methods in computer vision and are used in geometric camera calibration, 3D reconstruction, stereo vision and image mosaicking among other tasks. In this talk I show the surprising result that homographies are the apposite tool for relating image colors of the same scene when the capture conditions – illumination color, shading and device – change. Three applications of color homographies are investigated. First, I show that color calibration is correctly formulated as a homography problem. Second, I compare the chromaticity distributions of an image of colorful objects to a database of object chromaticity distributions using homography matching. In the color transfer problem, the colors in one image are mapped so that the resulting image color style matches that of a target image. I will show that a natural image color transfer can be reinterpreted as a color homography mapping. Experiments demonstrate that solving the color homography problem leads to more accurate calibration, improved color-based object recognition, and we present a new direction for developing natural color transfer algorithms.

Title: See What you think: Exploring a new concept of imaginative media

Abstract: In this talk, a new concept of imaginative media is to be introduced and explored to see if it could be developed into a feasible yet adventurous research project with high impact and significant expectations. Given the fact that whenever we read novels, the scenes, the events, and the characters will start to connect together and be visualized inside our brain via our imaginations. As a result, we are naturally moved or immersed into the stories even without the rehearsal play back of the stories in the form of videos or shows on the stage of a theatre. Along with the extensive research and enormous advancement across the areas of digital media, computer vision, computer graphics, virtual reality, machine learning, and computational neuroscience, new research can be initiated to learn from those collected brain signals and capture activities reflecting the imaginations inside brains. Computerized media production can then be further researched to visualize those imaginative scenes, events and stories to complete the adventurous exploration of the new concept: imaginative media. A systematic view of such exploration is given in the following diagram. Details of its possible research as well as challenges will be discussed, and suggestions and critiques are also welcome.

Dr Zicheng Liu

Title: Human Understanding with RGB-D Sensors and Its Applications

Abstract: I will talk about how advances in human understanding can enable novel interaction techniques in a collaborative environment. An example application involves augmenting a large touch display with a RGB-D sensor for casual meetings. On one hand, person detection and tracking, gesture and action recognition, and person identification can be leveraged to make the system more intelligent. On the other hand, there are serious limitations in the existing sensors and algorithms. I’ll give an overview on the progress of RGB-D based action recognition, and dive deeper into the problem of person re-identification and show how we learn depth features for person re-identification that are robust to illumination variations and less sensitive to cloth changes.

This includes development of several Bayesian parametric and non-parametric models, solving fundamental problems in processing multiple channel, multi-modal temporal and spatial data.

Title: Delivering Efficiencies in Health Care and Manufacturing

Abstract: This talk considers what to do when confronted with failures with current data or analysis. What can we do when current predictions for rare events are poor? Instead of focusing on rare event classification, for example, suicide prediction, we focus on identifying the riskiest events with minimal error. Such events are likely precursors to outliers of interest. We demonstrate our results through outlier detection in surveillance (leading to our start-up company iCetana, Australia) and in suicide risk prediction (implemented in in Barwon Health, Geelong, Australia). We discuss the challenges in data modeling, pitfalls and our outcomes. When data has special characteristics? We predict cancer toxicity risk, and show how we leverage the special characteristics of the data to build better predictive models. We share our insights we have learnt in our path from such data to models. When data is limited? We use Bayesian optimisation based methods to demonstrate how to accelerate the experimental process, the foundation of both product and process design. We show how we have been able to impact the discovery of novel materials and alloys.
