  author={Patrice Brault and Ali Mohammad-Djafari},
  journal={J. Electronic Imaging},
We describe a new fully unsupervised image segmentation method based on a Bayesian approach and a Potts-Markov random field (PMRF) model that are performed in the wavelet domain. A Bayesian segmentation model, based on a PMRF in the direct domain, has already been successfully developed and tested. This model performs a fully unsupervised segmentation, on images composed of homogeneous regions, by introducing a hidden Markov model (HMM) for the regions to be classified, and Gaussian… 

Scalable Region‐matching Motion Estimation Based on an Unsupervised Spatial Segmentation

It is shown that a hierarchical, region‐based, ME, can provide an interesting approach w.r.t. the necessity of ME robustness as well as its scalability, in a region (or object) ‐based compression scheme.

Extraction of Active Regions and Coronal Holes from EUV Images Using the Unsupervised Segmentation Method in the Bayesian Framework

The solar corona is the origin of very dynamic events that are mostly produced in active regions (AR) and coronal holes (CH). The exact location of these large-scale features can be determined by

Bayesian approach with prior models which enforce sparsity in signal and image processing

This review article proposes to use the Bayesian inference approach for inverse problems in signal and image processing, where the authors want to infer on sparse signals or images, and considers the probabilistic models to enforce the sparsity.

Bayesian Wavelet Domain Segmentation

A new version of the fully unsupervised segmentations of still images and 2D+T sequences is demonstrated by Bayesian methods, on the basis of a Hidden Markovian Model and a Potts‐Markov Random Field, in the pixel domain by taking advantage of the local decay property, or “peaky” distribution of the wavelet coefficients, in an orthogonal decomposition.

A multiscale random field model for Bayesian image segmentation

Simulations on synthetic images indicate that the new algorithm performs better and requires much less computation than MAP estimation using simulated annealing, and is found to improve classification accuracy when applied to the segmentation of multispectral remotely sensed images with ground truth data.

Bayesian segmentation and motion estimation in video sequences using a Markov-Potts model

A new approach for the segmentation of video sequences based on recent works on the Bayesian segmentation and fusion is reported here, making the assumption that the images follow a Potts-Markov random field model.

Unsupervised image segmentation using wavelet-domain hidden Markov models

A new unsupervised segmentation approach is developed by capturing the likelihood disparity of different texture features with respect to wavelet-domain HMMs, where three clustering methods are used to obtain the initial segmentation results.

Multiscale Bayesian segmentation using a trainable context model

A multiscale Bayesian segmentation algorithm which can effectively model complex aspects of both local and global contextual behavior is proposed which makes the method flexible by allowing both the context and the image models to be adapted without modification of the basic algorithm.

A deterministic relaxation method based on mean field annealing with a compound Gauss-Markov random (CGMRF) field model is proposed and a set of iterative equations for the mean values of the intensity and both horizontal and vertical line processes with or without taking into account some interaction between them are presented.

The authors describe the development of a deterministic algorithm for obtaining the global maximum a posteriori probability (MAP) estimate from an image corrupted by additive Gaussian noise that finds the global MAP estimate in a small number of iterations.
