The Multimodal Learning for Earth and Environment Workshop (MultiEarth 2023)
aims to harness the substantial amount of remote sensing data gathered over
extensive periods for the monitoring and analysis of Earth's ecosystems'health.
The subtask, Multimodal SAR-to-EO Image Translation, involves the use of robust
SAR data, even under adverse weather and lighting conditions, transforming it
into high-quality, clear, and visually appealing EO data. In the context of the
SAR2EO task, the presence of clouds or obstructions in EO data can potentially
pose a challenge. To address this issue, we propose the Clean Collector
Algorithm (CCA), designed to take full advantage of this cloudless SAR data and
eliminate factors that may hinder the data learning process. Subsequently, we
applied pix2pixHD for the SAR-to-EO translation and Restormer for image
enhancement. In the final evaluation, the team 'CDRL' achieved an MAE of
0.07313, securing the top rank on the leaderboard.
