Three Ways to Improve Semantic Segmentationwith Self-Supervised Depth EstimationLukas HoyerETH DaiETH ChenETH K oringUniversity of SahaETH Van GoolETH Zurich & KU deep networks for Semantic Segmentation re-quires large amounts of labeled training data, whichpresents a major challenge in practice, as labeling seg-mentation masks is a highly labor-intensive process. Toaddress this issue, we present a framework for semi-supervised Semantic Segmentation , which is enhanced byself-supervised monocular depth estimation from unlabeledimage sequences. In particular, we propose Three key con-tributions: (1) We transfer knowledge from features learnedduring self-supervised depth estimation to Semantic seg-mentation, (2) we implement a strong data augmentationby blending images and labels using the geometry of thescene, and (3) we utilize the depth feature diversity as wella
learning cycle (model training →query selection →an-notation →model training) [49, 62], it does not require a human in the loop to provide semantic segmentation labels as the human is replaced by a proxy-task SDE oracle. This greatlyimprovesflexibility,scalability,andefficiency,espe-cially considering crowdsourcing platforms for annotation.
