In the field of image processing corruption of images by Impulse noise due to different reasons is common. Impulse noise can degrade the visibility of image up to a great extent hence proper denoising technique for this kind of noise should be there. There are various type of filters used for the removal of impulse noise but every filter has its own limitations. It is observed that the techniques used for removing impulse noise have a problem that they cannot preserve the image details like edges at the high noise densities hence such techniques damage the important information of image during denoising. This problem can be solved by introducing a new approach of impulse noise removal which has the capability of edge preservation. The proposed filter is basically a combination of two different approaches which are bilateral filter and trimmed median filter.
