3D Shape Compression and Simplification

Supervisor: Dr Yonghuai Liu (yyl@aber.ac.uk)

Nowadays, it is easy to capture millions of points of the object of interest using the latest scanning systems [4]. While such a huge amount of points is useful for the description of the details of the object of interest, it presents a challenge for its pre-processing, visualization, and storage. This project intends to develop novel techniques [1, 2, 3] for the evaluation of the importance of the points for the representation of the overall geometry and local details, so that the levels of detail can be generated and transmitted for different applications.
