Context Encoding for Semantic Segmentation

CVPR 2018 Hang ZhangKristin DanaJianping ShiZhongyue ZhangXiaogang WangAmbrish TyagiAmit Agrawal

Recent work has made significant progress in improving spatial resolution for pixelwise labeling with Fully Convolutional Network (FCN) framework by employing Dilated/Atrous convolution, utilizing multi-scale features and refining boundaries. In this paper, we explore the impact of global contextual information in semantic segmentation by introducing the Context Encoding Module, which captures the semantic context of scenes and selectively highlights class-dependent featuremaps...
