Research on information hiding and recognition technology of halftone prints based on mobile phone
Results in Optics, 2021 This paper studies the method of embedding printing quantum information in the printed image and identifying whether the image carries hidden information by comparing the eigenvalues of the gray-level co-occurrence matrix of the image.

On Hidden Markov Processes with Infinite Excess Entropy
, 2012 We investigate stationary hidden Markov processes for which mutual information between the past and the future is infinite. It is assumed that the number of observable states is finite and the number of hidden states is countably infinite.

Local Realistic Model for the Dynamics of Bulk-Ensemble NMR Information Processing [PDF]
, 2001 We construct a local realistic hidden-variable model that describes the states and dynamics of bulk-ensemble NMR information processing up to about 12 nuclear spins.

Hidden information and regularities of information dynamics III
CoRR, 2012 This presentation's Part 3 studies the evolutionary information processes and regularities of evolution dynamics, evaluated by an entropy functional (EF) of a random field (modeled by a diffusion information process) and an informational path functional (IPF) on trajectories of the related dynamic process (Lerner 2012). The integral information measure

Information Geometry Approach to Parameter Estimation in Hidden Markov Models
, 2021 We consider the estimation of the transition matrix of a hidden Markovian process by using information geometry with respect to transition matrices. In this paper, only the histogram of $k$-memory data is used for the estimation. To establish our method,

Trade-off relations between measurement dependence and hidden information for factorizable hidden variable models [PDF]
QuantumThe Bell theorem is explored in terms of a trade-off relation between underlying assumptions within the hidden variable model framework. In this paper, recognizing the incorporation of hidden variables as one of the fundamental assumptions, we propose a ...

Short note on two output-dependent hidden Markov models [PDF]
, 2008 The purpose of this note is to study the assumption of mutual information independence", which is used by Zhou (2005) for deriving an output-dependent hidden Markov model, the so-called discriminative HMM (D-HMM), in the context of determining a ...
