Cascadic Multi-Receptive Learning for Multispectral Pansharpening

How to use?

  • Directly run: test.py for the single WV3 example
  • Directly run: test_mulExm.py for the multiple WV3 examples

Motivations

1. CML-resblock

A CML-resblock is proposed to extract information from different scales in a step-by-step manner. Specifically, every pixel of the output is able to perceive multi-scale information through a cascade-like connection strategy, which is an efficient and effective multi-receptive learning process.

2. Multiplication network structure

Inspired by the traditional multiplicative injection model for pansharpening, we design the novel multiplication network structure to learn the coefficients of the restoration mapping.
