Paper: U2Net

Summary

1. design a two-level nested U-structure for salient object detection;
2. capture more contextual information from different scales owing to the mixture of receptive fields of different sizes in ReSidual U-Blocks;
3. increases the depth of the whole architecture without significantly increasing the computational cost owing to the the pooling operations.
4. on the bottom level, we design a novel ReSidual U-block to extract intra-stage multi-scale features without degrading the feature map resolution; on the top level, U-Net like structure;
