Summary:
Color modification is one of commonly used image forgery techniques. In this paper, we present a new estimation method of the color modification using variance ratio of color difference model and wavelet transform. The color difference model is used to emphasize the distortion in CFA pattern caused by color modification. We define variance ratio value to determine the modified hue angle. Experimental results show that the proposed method has good results in detecting color modification forgery. Compared with conventional method, our method provides reasonable outputs.
