题目：Non-Photorealistic Rendering of Images

摘要：Computer Scientists have been inspired by artists to develop many non-photorealistic rendering techniques that can take an input image and produce a wide variety of artistic effects such as oil painting, watercolour, pointillist, etc. Their application can simply be for fun (e.g. to make consumer photographs more interesting), but there are also many other applications such as scientific visualisation, film production effects, technical illustration, etc.

This talk will overview several NPR techniques we developed, that aim to generate results that are relatively minimal rendering, in terms of using a combination of refined lines and regions and a small number of tones or colours. The aim is to achieve a rendering that is abstracted but retains sufficient elements from the original image so that (for example) it can be used to generate recognisable portraits..

Prof. Paul Rosin received the Ph.D. degree in Information Engineering from City University, London in 1988. At the beginning of 2000 he moved to the School of Computer Science & Informatics, Cardiff University. He is currently a Professor of Computer Vision at School of Computer Science & Informatics, Cardiff University, UK.

His research interests include the representation, segmentation, and grouping of curves, knowledge-based vision systems, early image representations, low level image processing, machine vision approaches to remote sensing, methods for evaluation of approximation algorithms, etc., medical and biological image analysis, mesh processing, non-photorealistic rendering and the analysis of shape in art and architecture. He has published more than 100 papers in international journals (e.g., PAMI, IJCV, TOG, TVCG, TIP, etc.) and conferences.
