Introduction

Joint training of neural-networks and graphical models has been previously reported by Ning et al. [22] for image segmentation, and by various groups in speech and language modeling [4, 21]. To our knowledge no such model has been successfully used for the problem of detecting and lo-calizing body part positions of humans in images.
