Image restoration by regularisation in uncorrelated transform domain
Sheung‐On Choy, Yuk‐Hee Chan, WC Siu · IEE Proceedings - Vision Image and Signal Processing · 2000
Conventional spatially adaptive regularised image restoration schemes weight the amount of regularisation according to the spatial content of an image. The authors first separately decorrelate the signals under analysis into uncorrelated components and then weight the amount of regularisation performed to these components accordingly. The proposed approach works better than conventional schemes, especially in edge regions.
