Scale-aware Neural Network for Semantic Segmentation of Multi-resolution Remote Sensing Images

no code implementations14 Mar 2021 Libo Wang, Ce Zhang, Rui Li, Chenxi Duan, Xiaoliang Meng, Peter M. Atkinson

However, MSR images suffer from two critical issues: 1) increased scale variation of geo-objects and 2) loss of detailed information at coarse spatial resolutions.

MACU-Net for Semantic Segmentation of Fine-Resolution Remotely Sensed Images

2 code implementations26 Jul 2020 Rui Li, Chenxi Duan, Shunyi Zheng, Ce Zhang, Peter M. Atkinson

In this Letter, we incorporate multi-scale features generated by different layers of U-Net and design a multi-scale skip connected and asymmetric-convolution-based U-Net (MACU-Net), for segmentation using fine-resolution remotely sensed images.
