Abstract

AbstractImage Enhancement is one of the most important concerns in Digital Image processing which is used to process the image so that we can view and assess the visual information it contains with greater clarity. In this Work a 2-step Image De-noising and Enhancement Algorithm is proposed i.e. the application of Improved Median Filter and Morphological Operations. In the First step Image is enhanced using a 3×3 neighborhood window processing and then using Morphological Operations to further enhance it. Our Method can remove salt-and-pepper-noise with noise level as high as 80%.KeywordsSpatial Domain TechniquesDigital Image ProcessingMathematical morphologyStructuring ElementMorphological OperationsSalt and Pepper Noise
