Photo morphing detection

Digital image manipulation software is now readily available on personal computers. It is therefore very simple to tamper with any image and make it available to others. Insuring digital image integrity has therefore become a major issue. Watermarking has become a popular technique for copyright enforcement and image authentication. The main aim of this project is to provide software which will help to detect the manipulation in the photo. Most digital cameras employ an image sensor with a color filter array such as shown on the left. The process of Demosaicing interpolates the raw image to produce at each pixel an estimate for each color channel. With proper analysis, traces of Demosaicing are exhibited in the peak of an analysis signal. The presence of Demosaicing indicates the image is from a digital camera rather than generated by a computer.
