Digital Image De-noising and Restoration method using Differential Filters for Improving the Image Quality

摘要

Digital photography is been enhanced in excess in past years, and it makes a leading trend for novel and innovative approach towards the forge images. The work is associated with extracting the tampered image in any form and processing it to obtain the required result. Commonly, in an image, it has some noise. The main aim is to de-noise the tampered image and reveal the original image without losing the image features (edges, corners and other sharp structures) by the restoration process. The de-noising is done by the median filter, the noise is been removed and then the restoration is done by the inverse filter.
