Abstract Image splicing is the most fundamental operation of creating an image forgery, thus the detection and localization of image splicing attract increasing attention recently. In this paper, a blind and passive approach of splicing localization is proposed based on original image estimation. By color filter array interpolation, the original image of the test image is estimated and the coherence of the pixels’ neighbor is re-constructed. Using a comparison between the test image and the estimated original one in edge pixels, the localization is implemented. Experimental results show the good performance of the proposed method.
