Signal Filtering: Noise Reduction and Detail Enhancement

  • Reference work entry
Handbook of Visual Display Technology

Abstract

In most display systems and imaging systems some form of image manipulation is necessary. This section discusses the use of operators that can be used to remove noise or provide detail enhancement. The techniques discussed here can be used both to correct the information to be displayed and to compensate for deficiencies in the display system. First linear shift-invariant operators will be presented from a mathematical point of view. Their application using convolution and Fourier techniques will be discussed. Several examples of linear shift-invariant operators, specifically those that can be used to smooth or enhance edges in images, will be presented. The section concludes with a presentation of order statistic filters and an example of an adaptive filter.
