An Adaptive approach to retrieve image affected by impulse noisefrom documents
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 3
Abstract
Abstract: Impulsive noise is sometimes called salt-and-pepper noise or spike noise is most oftenly occuringimage detoriation. An image containing salt-and-pepper noise will have dark pixels in bright regions and brightpixels in dark regions at random space. This type of noise can be caused by almost lost value of pixels, analogto-digitalconverter deficiencies, bit errors in transmission, fault in communication etc. The traditional filteringtechniques such as mean median and average are available to remove the noise from an image one of the mostoftenly used is Gaussian filtering technique. But these filtering techniques are not generic, where as suchtechniques are useful in preparing adaptive algorithm for the general purpose filters.
