Markov Random Field Models in Computer Vision
نویسنده
چکیده
A variety of computer vision problems can be optimally posed as Bayesian labeling in which the solution of a problem is de-ned as the maximum a posteriori (MAP) probability estimate of the true labeling. The posterior probability is usually derived from a prior model and a likelihood model. The latter relates to how data is observed and is problem domain dependent. The former depends on how various prior constraints are expressed. Markov Random Field Models (MRF) theory is a tool to encode contextual constraints into the prior probability. This paper presents a uniied approach for MRF modeling in low and high level computer vision. The uniication is made possible due to a recent advance in MRF modeling for high level object recognition. Such uniication provides a systematic approach for vision modeling based on sound mathematical principles.

Cluster-Based Image Segmentation Using Fuzzy Markov Random Field
Image segmentation is an important task in image processing and computer vision which attract many researchers attention. There are a couple of information sets pixels in an image: statistical and structural information which refer to the feature value of pixel data and local correlation of pixel data, respectively. Markov random field (MRF) is a tool for modeling statistical and structural inf...
