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…
Restoration of Atmospheric Turbulence-distorted Images via RPCA and Quasiconformal Maps
Chun Pong Lau, Yu Hin Lai, Lok Ming Lui
We address the problem of restoring a high-quality image from an observed image sequence strongly distorted by atmospheric turbulence. A novel algorithm is proposed in this paper t…
