This is typically done by hiding the message within a non-sensitive document. Steganalysis is the art and science of detecting such hidden messages. The task in steganalysis is to take an object (communication) and classify it as either a steganogram or a clean document. Most recent solutions apply classification algorithms from machine learning and pattern recognition, which tackle problems too complex for analytical solution by teaching computers to learn from empirical data. Part 1of the book is an introduction to steganalysis as part of the wider trend of multimedia forensics, as well as a practical tutorial on machine learning in this context. Part 2 is a survey of a wide range of feature vectors proposed for steganalysis with performance tests and comparisons. Part 3 is an in-depth study of machine learning techniques and classifier algorithms, and presents a critical assessment of the experimental methodology and applications in steganalysis.Key features: . Serves as a tutorial on the topic of steganalysis with brief introductions to much of the basic theory provided, and also presents a survey of the latest research.. Develops and formalises the application of machine learning in steganalysis; with much of the understanding of machine learning to be gained from this book adaptable for future study of machine learning in other applications. . Contains Python programs and algorithms to allow the reader to modify and reproduce outcomes discussed in the book.. Includes companion software available from the author's website.Wiley - IEEEMachine learningWavelets (Mathematics)Data encryption (Computer science)Machine learning.Wavelets (Mathematics)Data encryption (Computer science)006.3/1SCI067000bisacshSchaathun Hans Georg845658CaBNVSLCaBNVSLCaBNVSLBOOK9910137612703321Machine learning in image steganalysis1887878UNINA01435nam 2200433 450 991081623580332120200520144314.088-921-5120-7(CKB)5120000000186241(MiAaPQ)EBC2067842(Au-PeEL)EBL2067842(CaPaEBR)ebr11069276(OCoLC)911001650(EXLCZ)99512000000018624120150711h20122012 uy 0itaurcnu||||||||rdacontentrdamediardacarrierLegislatori regionali e legislazione Europea le prospettive delle regioni italiane nella fase ascendente di formazione del diritto dell'Unione europea dopo il Trattato di Lisbona /Francesco PaternitiTurin, [Italy] :G.
