Supplementary Material for Mask Propagation for Efficient Video Semantic Segmentation

We organize our supplementary material as follows: In Section A, we present more analytical results on VSPW dataset. In Section B, we provide more ablation studies on Cityscapes dataset. In Section D, we provide computational cost analysis and training details. In Section E, we provide comparison with bi-directional optical flow. A.1 Explanation of Video Consistency Following [3], we use Video Consistency (VC) to evaluate the category consistency among adjacent frames in the videos.
