We propose a simple method for extracting stronger labels from weak cropland labels and an unsupervised segmentation of satellite imagery. We show, in a scenario in Kenya where we only have 33 human-annotated labels, that adding strong labels mined by our method increases the F1 score for the cropland category from 0.53 (without mining) to 0.84. |
