Koç, A.Özaktaş, Haldun M.Hesselink L.2016-02-082016-02-0820110277-786Xhttp://hdl.handle.net/11693/28418Conference name: Proceedings of SPIE, Three-Dimensional Imaging, Visualization, and Display 2011Date of Conference: 27–28 April 2011The class of two-dimensional non-separable linear canonical transforms is the most general family of linear canonical transforms, which are important in both signal/image processing and optics. Application areas include noise filtering, image encryption, design and analysis of ABCD systems, etc. To facilitate these applications, one need to obtain a digital computation method and a fast algorithm to calculate the input-output relationships of these transforms. We derive an algorithm of NlogN time, N being the space-bandwidth product. The algorithm controls the space-bandwidth products, to achieve information theoretically sufficient, but not redundant, sampling required for the reconstruction of the underlying continuous functions. © 2011 SPIE.EnglishABCD opticsFast algorithmsLinear Canonical TransformsQuadratic-Phase SystemsTransformsBandwidthImaging systemsMathematical transformationsOpticsSignal processingVisualizationContinuous functionsDesign and analysisDigital computationFast algorithmsFast and accurate algorithmsImage encryptionsLinear canonical transformSpace-bandwidth productAlgorithmsConference Paper10.1117/12.884676
