Topic Description and Justification

An exciting development over the last decade has been the gradually
widespread adoption of probabilistic graphical models (PGMs) in many
areas of computer vision and pattern recognition. Many problems in
computer vision can be viewed as the search, in a specific domain, for
a coherent global interpretation and understanding from local,
uncertain, and ambiguous observations. Graphical models provide a
unified framework for representing the observations and the
domain-specific contextual knowledge, and for performing recognition
and classification through rigorous probabilistic inference. In
addition, PGMs readily capture the correlations and dependencies among
the observations, as well as between observations and domain or
commonsense knowledge, and allow systematic quantification and
propagation of the uncertainties associated with data and inference.

Graphical models can be classified into directed and undirected
models. The directed graphs include Bayesian Networks (BNs) and Hidden
Markov Models (HMMs), while the undirected graphs include Markov
Random Fields (MRFs) and

Conditional Random Fields (CRFs). Both directed and undirected
graphical models have been widely used in computer vision. For
example, HMMs are used in computer vision for motion analysis and
activity understanding, while MRFs are extensively used for image
labeling, segmentation, and stereo reconstruction. The latest research
uses BNs in computer vision for representing causal relationships such
as for facial expression recognition, active vision, visual
surveillance, and for data mining and pattern discovery in pattern
recognition. CRFs provide an appealing alternative to MRFs for
supervised image segmentation and labeling, since they can easily
incorporate expressive, non-local features. Another emerging trend is
to use graphical models to integrate context and prior knowledge with
visual cues in vision and multimedia systems.  Despite their
importance and recent successes, PGMs' use in computer vision still
has tremendous room to expand in scope, depth, and rigor. Their use is
especially important for robust and high level visual understanding
and interpretation.

This special issue is dedicated to promoting systematic and rigorous
use of PGMs for various problems in computer vision. We are interested
in applications of PGMs in all areas of computer vision, including
(but not limited to):

1) image and video modeling 6) motion estimation and tracking
2) image and video segmentation 7) new inference and learning (both structure and parameters) theories for
3) object detection graphical models arising in vision applications
4) object and scene recognition 8) generative and discriminative models
5) high level event and activity understanding 9) models incorporating contextual, domain, or commonsense knowledge

Paper submission and review
The papers should be submitted online through TPAMI’s Manuscript
Central site, with a note/tag designating the manuscript to this
special issue. All submissions will be peer-reviewed by at least 3
experts in the field. Priority will be given to work with high novelty
and potential impacts. We will return without review submissions that
we feel are not well aligned with our goals for the special issue.
