  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.
