Would be interested in from anyone who has experience with image filtering techniques for noise reduction that simultaneously ENHANCE edges. Normally, these two operations are mutually exclusive (as noise reduction can tend to BLUR edges, not sharpen them). There exist non-linear approaches that achieve this goal (although tending to be computationally very intensive). Application is x-ray fluoroscopy (noise is Poisson). Goal is to reduce the Poisson noise while providing edge enhancement. Anecdotes, experience, pointers to articles, etc. would be appreciated.
