Researchers have developed a new method called cross-scale pretraining to improve self-supervised learning for low-resolution satellite imagery. This technique incorporates high-resolution imagery to enhance the learning of representations for mid-resolution images, leading to better performance in downstream semantic segmentation tasks. The spatial affinity component, when added to existing self-supervised learning frameworks, demonstrated superior results compared to models pretrained solely on either high- or mid-resolution data.
