We address the problem of
segmenting 3D scan data into objects or object classes. Our
segmentation framework is based on a subclass of Markov Random Fields
(MRFs) which support efficient graph-cut inference. The MRF
models incorporate a large set of diverse features and enforce
the preference that adjacent scan points have the same classification
label. We use a recently proposed maximum-margin framework to
discriminatively train the model from a set of labeled scans; as a
result we automatically learn the relative importance of the features
for the segmentation task.
