简介
Street-level scene segmentation aims to label each pixel of street-view images into specific semantic categories. It has been attracting growing interest due to various real-world applications, especially in the area of autonomous driving. However, this pixel-wise labeling task is very challenging under the complex street-level scenes and large-scale object categories. Motivated by the scene layout of street-view images, in this work we propose a novel Spatial Gated Attention (SGA) module, which automatically highlights the attentive regions for pixel-wise labeling, resulting in effective street-level scene segmentation. The proposed module takes as input the multi-scale feature maps based on a Fully Convolutional Network (FCN) backbone, and produces the corresponding attention mask for each feature map. The learned attention masks can neatly highlight the regions of interest while suppress background clutter …
