An algorithm to detect the forged part in an image

Image forgery detection algorithms are used to verify the authenticity of digital images. In literature, different algorithms have been proposed to detect the authenticity of an image, for example, methods based on copy-move forgery detection, histogram analysis, methods based on color filter array, etc. The objective of this paper is to present an image forgery detection algorithm based on color filter array (CFA) interpolated images. Proposed algorithm has been applied on different images in-order to identify in which bayer pattern and map filtering parameter the forged part is clearly visible.
