Is there a training and optimization algorithm for 2-D (two dimensional) conditional random fields (CRF) suited for classification of imagery?
Has anyone used CRF package in R (http://crf.r-forge.r-project.org/html/CRF-package.html) for image classification? I would like to have a view of a working example code. Thanks.

Look up on Markov Random Fields. Here's a link to a paper you might be interested in: Patric Perez: Markov Random Fields and Images (1998).

classification of imagery usually involves bag of words and feature pooling and stuff, whereas conditional random field is for labeling sequential data. so it might not be appropriate to use crf in this scenario.

I do not think it will work alone. Since image classification is about scaling and affine transformation, so the key feature for accurate image classification is preprocessing not classification algorithm.
