Abstract
We propose an approach to include contextual features for labeling
images, in which each pixel is assigned to one of a finite set of
labels. The features are incorporated into a probabilistic framework,
which combines the outputs of several components. Components differ
in the information they encode. Some focus on the image-label mapping,
while others focus solely on patterns within the label field. Components
also differ in their scale, as some focus on fine-resolution patterns
while others on coarser, more global structure. A supervised version
of the contrastive divergence algorithm is applied to learn these
features from labeled image data. We demonstrate performance on two
real-world image databases and compare it to a classifier and a Markov
random field.
