Figure. From left to right. Overhead view of hyperspectral data with methane plumes as red masks (top row) overlayed on the observed terrain (bottom row). The columns are ground-truth (first column), naive single-band prediction (center column), and H-mrcnn ensemble prediction (right column). The core detector is the mask-rcnn detector with ResNet-101 as backbone.
