摘要: An effective framework for passive-blind color image tampering detection is presented in this paper. The proposed statistical features are generated by applying Markovian rake transform to luminance component. the application of Markov process difference arrays which derived from quantized block discrete cosine 2-D with multiple sizes. efficacy thus has been confirmed over a recently established large-scale dataset designed detection, some relevant issues have addressed and corresponding adjustment measures taken. initial tests using classifiers on real-life forged images available Internet show signs promise as well challenge encountered research community detection.
