Abstract

Understanding of visual scenes relies more and more on dense pixel-wise classification obtained via deep fully convolutional neural networks. However, due to the nature of the networks, predictions often suffer from blurry boundaries and ill-segmented shapes, fueling the need for post-processing. This work formulates the standard semantic segmentation problem in terms of distance regression. We show that it is possible to train a multi-task fully convolutional neural network that builds more regular segmentations than those produced by existing methods based on direct dense classification.
