Review and Analysis of Image De-noising Techniques for Impulse Noise Removal.

Image noise removal is most important phenomena of image processing. Filtering method is emphasized for all proposed de-noising schemes. In this paper, we have study bout the different algorithms based on non-linear filter to remove the impulse noise from images. Different image noise removal algorithms are analyzed and some parameters are varied in a wide range to study the results of different algorithms. Mathematical analysis show the quality of some de-noising techniques is better than the other methods. Hardware implementations of some techniques are very easy; because less number of calculations required removing the noise.
