Directional regularisation for constrained iterative image restoration
Sang Hwa Lee, Nam Ik Cho, Jong-Il Park · Electronics Letters · 2003
Image restoration is an ill-posed inverse problem, which has introduced the regularisation method to suppress over-amplification. However, the regularisation causes the reblurring problem and does not eliminate ringing artefacts effectively. A directional regularisation approach is proposed to reduce the reblurring problem and the ringing artefacts in iterative image restoration.
