摘要: Computer graphics rendering software is capable of generating highly photorealistic images that can be impossible to differentiate from photographic images. As a result, the unique stature photographs as definitive recording events being diminished (the ease with which digital manipulated is, course, also contributing this demise). To end, we describe method for differentiating between and Specifically, show statistical model based on first-order higher order wavelet statistics reveals subtle but significant differences
