MultiEarth 2022 -- The Champion Solution for Image-to-Image Translation Challenge via Generation Models
This is an incremental improvement for remote sensing image translation, addressing a specific competition benchmark.
The paper tackled generating RGB Sentinel-2 imagery from Sentinel-1 VV & VH data in the MultiEarth 2022 challenge, achieving a top-ranked MAE score of 0.02795.
The MultiEarth 2022 Image-to-Image Translation challenge provides a well-constrained test bed for generating the corresponding RGB Sentinel-2 imagery with the given Sentinel-1 VV & VH imagery. In this challenge, we designed various generation models and found the SPADE [1] and pix2pixHD [2] models could perform our best results. In our self-evaluation, the SPADE-2 model with L1-loss can achieve 0.02194 MAE score and 31.092 PSNR dB. In our final submission, the best model can achieve 0.02795 MAE score ranked No.1 on the leader board.
