The estimated mixture is used to compute the so called log-likelihood transformation of the original image. We show that image manipulations of different type may be visible in a suitably designed log-likelihood image. Unlike other methods the forgery detection based on local statistical model is rather non-specific and suitable to emphasize various traces of possible image tampering without any prior information. cav_un_auth*0265017 6th International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP 2010) Darmstadt 15.10.2010-17.10.2010 DE 2011 IN 3 http://hdl.handle.net/11104/0189094 2010 sborník, databáze příspěvků cav_un_epca*0348591 2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing 978-0-7695-4222-5 579 582 Los Alamitos, California IEEE computer society 2010 Echizen Isao 340 Pan Jeng-Shyang 340 Fellner Dieter 340 Nouak Alexander 340 Kuijper Arjan 340 Jain Lakhmi C. 340
