Boundary-Aware Feature Propagation for Scene Segmentation

ICCV 2019poster

In this work, we address the challenging issue of scene segmentation. To increase the feature similarity of the same object while keeping the feature discrimination of different objects, we explore to propagate information throughout the image under the control of objects' boundaries. To this end, w…

Semantic Correlation Promoted Shape-Variant Context for Segmentation

CVPR 2019oral

Context is essential for semantic segmentation. Due to the diverse shapes of objects and their complex layout in various scene images, the spatial scales and shapes of contexts for different objects have very large variation. It is thus ineffective or inefficient to aggregate various context informa…

Context Contrasted Feature and Gated Multi-Scale Aggregation for Scene Segmentation

CVPR 2018poster

Scene segmentation is a challenging task as it need label every pixel in the image. It is crucial to exploit discriminative context and aggregate multi-scale features to achieve better segmentation. In this paper, we first propose a novel context contrasted local feature that not only leverages the…
