A Method of Adaptive Smoothing and Edge Enhancement

reportActive / Technical Report | Accession Number: ADA041909 | Open PDF

Abstract:

A local operator, SWAC, is introduced which identifies image neighborhoods that are noisy and do not contain any boundary. An adaptive smoothing function, guided by the response of SWAC, successfully smooths noisy regions in images without degrading edges. The response of SWAC is also successfully used as a weighting function to suppress spurious responses of an edge detector operating in a noisy environment.
