Fully Convolutional Networks for Semantic Segmentation

Evan Shelhamer, Jonathan Long, Trevor Darrell

Short summary

Fully convolutional networks (FCNs) achieve state-of-the-art semantic segmentation by training end-to-end, pixels-to-pixels, improving mean Intersection over Union (mIoU) by 30% to 67.2% on PASCAL VOC 2012.

Key points

  • Fully convolutional networks (FCNs) are introduced for end-to-end semantic segmentation.
  • FCNs achieve a 30% relative improvement in mean IoU (to 67.2%) on PASCAL VOC 2012.
  • A skip architecture combines deep semantic and shallow appearance information for detailed segmentations.
  • Inference is efficient, taking only 0.1 seconds for a typical image.

Abstract

Convolutional networks are powerful visual models that yield hierarchies of features. We show that convolutional networks by themselves, trained end-to-end, pixels-to-pixels, improve on the previous best result in semantic segmentation. Our key insight is to build "fully convolutional" networks that take input of arbitrary size and produce correspondingly-sized output with efficient inference and learning. We define and detail the space of fully convolutional networks, explain their application to spatially dense prediction tasks, and draw connections to prior models. We adapt contemporary classification networks (AlexNet, the VGG net, and GoogLeNet) into fully convolutional networks and transfer their learned representations by fine-tuning to the segmentation task. We then define a skip architecture that combines semantic information from a deep, coarse layer with appearance information from a shallow, fine layer to produce accurate and detailed segmentations. Our fully convolutional networks achieve improved segmentation of PASCAL VOC (30% relative improvement to 67.2% mean IU on 2012), NYUDv2, SIFT Flow, and PASCAL-Context, while inference takes one tenth of a second for a typical image.
