Markov Random Fields (MRFs) are a popular and well motivated model for many medical image processing tasks such as segmentation. Discriminative Random Fields (DRFs), a discriminative alternative to the traditionally generative MRFs, allow tractable computation with less restrictive simplifying assumptions, and achieve better performance in many tasks. In this paper, we investigate the tumor segmentation performance of a recent variant of DRF models that takes advantage of the powerful Support Vector Machine (SVM) classification method. Combined with a powerful Magnetic Resonance (MR) preprocessing pipeline and a set of alignment-based features, we evaluate theuse of SVMs, MRFs, and two types of DRFs as classifiers for threes egmentation tasks related to radiation therapy target planning for brain tumors, two of which do not rely on contrast agent enhancement. Our results indicate that the SVM-based DRFs offer a significant advantageover the other approaches.
