Originally proposed in 1965 for standard problems of channel and source coding in communications, permutation codes can also provide optimum solutions in two relevant fields: steganography (foiling hidden information detection tests) and counterforensics (foiling forensic detection tests). In the first scenario, permutation codes have been shown to implement optimum perfect universal steganography (that is to say, steganography with maximum information embedding rate, undetectable and only relying on the empirical distribution of the host) for histogram-based hidden information detectors. In the second scenario, permutation codes have been shown to implement minimum-distortion perfect counterforensics (that is to say, forgeries which are undetectable and as close as possible to a target forgery) for histogram-based forensic detectors. Interestingly, both of these developments have revealed connections with compression through theoretical bounds from the mathematical theory of information. In steganography, the long-acknowledged duality between perfect steganography and lossless compression has been made explicit by permutation coding. On the other hand, a connection between counterforensics, lossy compression and histogram specification is also shown.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123310848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reconstruction is based on a phase shifting approach, where the CCD sensor and the reference wave are moved simultaneously along different positions in x and y. An inclination of the reference wave induces a phase shift when reference wave and CCD sensor are moved. In contrast to temporal phase shifting methods, the approach does not require any of the images to be recorded at the same positions, which is an important step towards the long-term prospect of a hand held holographic sensor that can measure wave fields with high resolution just by movement of the hand. Also, the phase shifts and shifts of the CCD sensor do not necessarily need to be determined from the experimental setup. They can also be reconstructed from the recorded images if there is a region in Fourier space where no aliases are present. We present a model for the recording process and an approach for the reconstruction, as well as experimental results demonstrating the validity of the new method.","PeriodicalId":183646,"journal":{"name":"2014 13th Workshop on Information Optics (WIO)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127760993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
