Other AbstractSplicing manipulation is a common way for image forgeries, according to the difference of color shift between splicing areas and original part, we put forward a kind of auto-detection method for splicing images based on estimation of color shift. First of all, the suspicious image is divided into small sub-blocks, size of which are n小n. After that an improved average color deviation calculation method is applied to estimate color shift of each sub-blocks. And then the collection of sub-blocks is set in radial directions of top, left, right on the suspicious image as the reference region, with scale selection of edge sub-blocks, color shift between each sub-block and reference is calculated. At last, the splicing area can be localized automatically by the comparison of color shift distance with empirical threshold. As a result, the inconsistency of color shift in a splicing image can be exposed after the localization of the splicing area. Experiments show that the proposed method can detect splicing images and localize splicing area automatically, and provide a scientific and quantitative evidence for the detection of splicing manipulation.
