Variational models for joint subsampling and reconstruction of turbulence-degraded images
Chun Pong Lau, Yu Hin Lai, Lok Ming Lui
Turbulence-degraded image frames are distorted by both turbulent deformations and space-time-varying blurs. To suppress these effects, we propose a multi-frame reconstruction schem…
Image retargeting via Beltrami representation
Chun Pong Lau, Chun Pang Yung, Lok Ming Lui
Image retargeting aims to resize an image to one with a prescribed aspect ratio. Simple scaling inevitably introduces unnatural geometric distortions on the important content of th…
Teichmüller extremal mapping and its applications to landmark matching registration
Lok Ming Lui, Ka Chun Lam, Shing-Tung Yau +1
Registration, which aims to find an optimal 1-1 correspondence between shapes, is an important process in different research areas. Conformal mappings have been widely used to obta…
Beltrami Representation and its applications to texture map and video compression
Lok Ming Lui, Ka Chun Lam, Tsz Wai Wong +1
Surface parameterizations and registrations are important in computer graphics and imaging, where 1-1 correspondences between meshes are computed. In practice, surface maps are usu…
