Abstract
Major artifacts of the spectral subtraction signal restoration technique are the presence of harmonic patterns and blurring effects for images, and the presence of short tone bursts of varying frequency for speech signals. In this paper, we discuss several techniques developed to reduce these artifacts. Examples are shown to illustrate the performance of these techniques.
