de Almeida-Thouless Stability and Replica Symmetry Breaking in a Hybrid Watermarking Model with Image and Message Decoding
Tatsuya Uezu, Kao Hayashi, Masaki Kawamura
We investigate the de Almeida-Thouless (AT) stability of the replica symmetric (RS) solution for a spread-spectrum watermarking model incorporating Bayes-estimation-based image res…
Reconstructing Sparse Signals via Greedy Monte-Carlo Search
Kao Hayashi, Tomoyuki Obuchi, Yoshiyuki Kabashima
We propose a Monte-Carlo-based method for reconstructing sparse signals in the formulation of sparse linear regression in a high-dimensional setting. The basic idea of this algorit…
Statistical mechanical evaluation of spread spectrum watermarking model with image restoration
Masaki Kawamura, Kao Hayashi, Tatsuya Uezu +1
In cases in which an original image is blind, a decoding method where both the image and the messages can be estimated simultaneously is desirable. We propose a spread spectrum wat…
