UNMIXING-BASED DENOISING AS A PRE-PROCESSING STEP FOR CORAL REEF ANALYSIS
Hyperspectral remote sensing Coral Denoising Water Derivative Features Spectral Unmixing
2017/7/12
Coral reefs, among the world’s most biodiverse and productive submerged habitats, have faced several mass bleaching events due to climate change during the past 35 years. In the course of this century...
CUBESAT-DERIVED DETECTION OF SEAGRASSES USING PLANET IMAGERY FOLLOWING UNMIXING-BASED DENOISING: IS SMALL THE NEXT BIG?
Mediterranean seagrass Posidonia oceanica Planet CubeSats Unmixing-based denoising Depth-invariant index Support Vector Machines
