Baraniuk, "Edge Localized Image Sharpening via Reassignment with Application to Computed Tomography," vol. 4121, 2000.https://hdl.handle.net/1911/19860Conference PaperTraditional filtering methods operate on the entire signal or image. In some applications, however, errors are concentrated in specific regions or features. A prime example is images generated using computed tomography. Practical implementations limit the amount of high frequency content in the reconstructed image, and consequently, edges are blurred. We introduce a new post-reconstruction edge enhancement algorithm, based on the reassignment principle and wavelets, that localizes its sharpening exclusively to edge features. Our method enhances edges without disturbing the low frequency textural details.engImage enhancementedge sharpeningcomputed tomographywaveletsreassignmentConference paperImage enhancementedge sharpeningcomputed tomographywaveletsreassignmenthttp://dx.doi.org/10.1117/12.402443
