Abstract:

This paper presents a hue modification detection method to identify the true meaning of a digital image. To detect an image forgery, we proposed a robust forensics scheme for detecting hue modification. First, separate the photo response non-uniformity (PRNU) by a color filter array forms a pattern independent of others, the position of each PRNU pixel will do not overlap. We designed a forensic scheme for estimating the hue modification by using PRNU from each color channel of an image. We also proposed an efficient estimation scheme and an algorithm for detection and partial manipulation the results defines that the proposed method distinguishes the hue modification of an image and it estimates the degree of change. This paper improves the saturation modification of the image and achieves the purity of the image.
