Abstract:Modelling long-range contextual relationships is critical for pixel-wise prediction tasks such as semantic segmentation. However, convolutional neural networks (CNNs) are inherently limited to model such dependencies due to the naive structure in its building modules (e.g., local convolution kernel). While recent global aggregation methods are beneficial for longrange structure information modelling, they would oversmooth and bring noise to the regions contain fine details (e.g., boundaries and small objects),… Show more
