ADAPTIVE APPROACH TO RETRIEVE IMAGE AFFECTED BY IMPULSE NOISE

Impulsive noise is a kind of noise in sim literature it is also called salt-and-pepper noise or spike noise is most oftenly occuring image detoriation.It is a type of noise which has black pixel in white region and white pixel in black region, this type of noise can be caused by almost lost value of pixels, inefficient analog-to-digital converter, change in bit value during transmission eavesdrops, fault and failure in communication etc.The traditional filtering techniques such as mean median and average are available to remove the noise from an image one of the most oftenly used is Gaussian filtering technique.But these filtering techniques are not generic, where as such techniques are useful in preparing adaptive algorithm for the general purpose filters.
