Focus recovery based on the linear canonical transform
http://dbpedia.org/resource/Focus_recovery_based_on_the_linear_canonical_transform an entity of type: WikicatOptics
For digital image processing, the Focus recovery from a defocused image is an ill-posed problem since it loses the component of high frequency. Most of the methods for focus recovery are based on depth estimation theory. The Linear canonical transform (LCT) gives a scalable kernel to fit many well-known optical effects. Using LCTs to approximate an optical system for imaging and inverting this system, theoretically permits recovery of a defocused image.
