Unsupervised detection of ash dieback disease (Hymenoscyphus fraxineus) using diffusion-based hyperspectral image clustering. (arXiv:2204.09041v1 [cs.CV])
cs.LG updates on arXiv.org arxiv.org
Ash dieback (Hymenoscyphus fraxineus) is an introduced fungal disease that is
causing the widespread death of ash trees across Europe. Remote sensing
hyperspectral images encode rich structure that has been exploited for the
detection of dieback disease in ash trees using supervised machine learning
techniques. However, to understand the state of forest health at
landscape-scale, accurate unsupervised approaches are needed. This article
investigates the use of the unsupervised Diffusion and VCA-Assisted Image
Segmentation (D-VIS) clustering algorithm for the detection of …
