Improved Matching Technique in Digital Image Region Duplication

摘要

Region duplication is the common type of image tampering which copies a part of an image and moved in that same image. Many techniques have been proposed to detect such tampering but it is difficult to find the true matched region in an image. Over many existing methods SIFT considered to be efficient one in matching duplicated region under different kinds of transformations, but fails when the image has reflection in it. A method with capability of detecting duplication under reflection is used in this work to make a detection system even more accurate and efficient.
