Multi-scale spatial-spectral fusion based on multi-input fusion calculation and coordinate attention for hyperspectral image classification

作者:

Highlights:

• Multi-scale spectral features and spatial features are acquired and fused.

• The three-branch and the concatenation module are used to obtain multi-scale features.

• Use coordinate attention mechanism to enhance distinguishability characteristics.

• Combine multiple input patches according to the classification effect.

• Consider accuracy and precision to fuse the output results of multiple patches.
