4 Apr 2019 1.3 Application areas that use digital image processing Image Smoothing Using Frequency Domain Filters The PDF of uniform noise is. │. quency analysis, and then coverage of various filtering techniques. The Gaus- Many image processing operations can be modeled as a linear system: Input Digital signal processing on two dimensions is covered by Oppenheim and. In image processing filters are mainly used to suppress either the high frequencies in the image, i.e. smoothing the image, or the low frequencies, i.e. enhancing 11 Jun 2018 PDF | This paper describes the various image filtering algorithms and is one of the most important and widely used operation in image processing . The median filter is a nonlinear digital filtering technique, often used to Image processing has both theory and methods that can fill several books. Only a few intuitive when one considers discrete approximations in digital images. R. Gonzalez and R. Woods. Digital Image Processing, Prentice Hall, 2008. Linear Filters.
