Professional Activities        

I am on the editorial boards of IEEE Transactions on Visualization and Computer Graphics and The Visual Computer.

I was conference co-chair of Computation Visual Media (CVM) 2016 and Eurographics Symposium on Geometry Processing (SGP) 2014, and program co-chair of 3DOR (3D Object Retrieval) 2021 workshop.

Research Interests

• Computer Graphics
• Geometry Processing
• Computer Vision
• Image Processing

In other words, my research interests include creating nice images/shapes/animation automatically or with a small amount of user interaction and developing automatic algorithms to understand and analyse visual data and present data in an interesting manner.

If you are an undergraduate or master student interested in doing research in these exciting and highly rewarded fields, send me an email.

Some potential projects (but more are possible).

• 3D Shape Analysis using Deep Learning

  PROJECT TITLE: 3D Shape Analysis using Deep Learning

  KEYWORDS:3D geometry, machine learning, convolutional neural networks, shape

  DESCRIPTION:3D shapes have proliferated in recent years, due to the availability of low-cost 3D cameras such as Kinect and Occipital Structure sensors, and their wide applicability in manufacturing design, entertainment industry, digital earth, 3D printing, and virtual reality etc. Online databases such as Trimble 3D Warehouse contain millions of 3D shapes. It is an increasing challenge to describe complicated 3D shapes effectively and analyse shapes at a high-level, e.g. to recognise objects in a scene or to find reusable parts for manufacturing design. Deep learning has shown to be an effective approach in image analysis, achieving state-of-the-art performance in many tasks. The aim of the project is to develop deep learning techniques for 3D shape analysis.

• 3D Model Segmentation and Analysis

  PROJECT TITLE: 3D Model Segmentation and Analysis

  KEYWORDS: geometric models, shape analysis, segmentation, computer graphics, computer-aided design

  DESCRIPTION: With the development of 3D acquisition techniques, 3D models are now widely available and used in various applications. The demand for model analysis and understanding is thus ever increasing. Model segmentation, i.e. decomposing a model into a set of disjoint, meaning pieces (e.g. limbs and torso of an animal) or ones which satisfy other desirable criteria (e.g. with consistent shape or texture constraint). Model segmentation is an important step towards model understanding and has broad applications, such as reverse engineering in computer-aided geometric design, as well as simplification, collision detection, morphing and animation in computer graphics. This project aims at investigating effective and efficient solutions to model segmentation, using various computer vision techniques.

• Image and Video Vectorisation

PROJECT TITLE: Image and Video Vectorisation

KEYWORDS: image and video processing, computer graphics, image compression, image editing

DESCRIPTION: Vector graphics are well-known to offer various advantages over raster graphics. Many images, ranging from artistic work to captured photos, have relatively uniform or smoothly changing colours, and representing them using vector graphics can lead to significant savings of storage and network bandwidth. They are also resolution-independent and easy to edit, making them particularly suitable for animation transmitted over the Internet, such as SVG and Shockwave Flash. Manual creation of vectorised graphics takes a huge amount of time. The aim of this project is to investigate robust and efficient solutions to computer aided generation of vectorised images and videos.

• Modelling and Transferring Geometric Details over 3D Shapes

  PROJECT TITLE: Modelling and Transferring Geometric Details over 3D Shapes

  KEYWORDS: geometric models, shape analysis, computer graphics, computer vision

  DESCRIPTION: The recent development of 3D acquisition techniques allows complicated geometric models with fine details to be digitally captured. In many cases, such details reveal the essential geometric textures or the particular artistic styles (e.g. sculpture, woodcut etc.) of the objects. Modelling geometric textures or styles from one object makes it possible to reproduce similar textures or styles over new models. This not only brings richness to new objects, but also allows newly created objects to be stylised as exemplars. In this project, shape analysis and computer vision techniques will be utilised to appropriately analyse and model the geometric details and further algorithms to transfer such models will be investigated.

If you are interested in applying for China Scholarship Council funding: Cardiff University is an official partner of China Scholarship Council (CSC). There are schemes for joint funding with tuition fees waived. If you are interested in applying for CSC funding, please discuss this with me as additional deadline/steps may apply.
