Abstract

In image forgeries the image data is copied and changes done in image structure, inconsistencies in an imaging feature called lateral chromatic aberration (LCA). A new method for detecting forged image regions to identify localized LCA inconsistencies. This proposed method has a new statistical model that shows the inconsistency between global and local estimates of LCA. Using an efficient LCA estimation algorithm, we implement a block matching algorithm called diamond search. It efficiently measures the LCA in a localized regions and performs with different experiments, characterize the effect of up sampling factor and forgery size on forgery detection. Calculates the performance with standard systems to reduce estimation time.
