Digital Image Forgery Detection by Contrast Enhancement

IOSR Journal of Computer Engineering, 2014
For decades, photographs have been used to document space-time events and they have often served as evidence in courts. Today, powerful digital image editing software makes image modifications straightforward. This undermines our trust in photographs and, in particular, questions pictures as evidence for real-world events.
