Steganography schemes based on a deflection criterion for embedding posses clear advantage against heuristics as they provide direct link between theoretical detectability and empirical performance. However, this depends the accuracy of cover stego model underlying scheme. In work we propose an original steganography scheme realistic sensor noise, taking into account camera model, ISO setting p...

Reeb spaces, as well their discretized versions called Mappers, are common descriptors used in topological data analysis, with plenty of applications various fields science, such computational biology and visualization, among others. The stability quantification the rate convergence Mapper to space has been studied a lot recent works (Brown et al. CoRR. arXiv:1909.03488 , 2019; Carrière Oudot F...
