Course Description

Computational Quasiconformal Geometry (CQC) studies the deformation pattern between shapes. It has been widely used in applied mathematics and applied in various applications, such as image processing, medical image analysis, computer graphics, computer vision and so on. This course gives an overview of CQC from fundamental concepts, theoretical aspects, computational aspects as well as real-world applications. It is expected that students will get a better idea of this fascinating topic after taking the course.

Honesty in Academic Work

The Chinese University of Hong Kong places very high importance on honesty in academic work submitted by students, and adopts a policy of zero tolerance on cheating and plagiarism. Any related offence will lead to disciplinary action including termination of studies at the University. Although cases of cheating or plagiarism are rare at the University, everyone should make himself / herself familiar with the content of the following website:

and thereby help avoid any practice that would not be acceptable.
