Identification of Floating Green Tide in High-Turbidity Water from Sentinel-2 MSI Images Employing NDVI and CIE Hue Angle Thresholds

Journal of Marine Science and Engineering
Remote sensing technology is widely used to obtain information on floating green tides, and thresholding methods based on indices such as the normalized difference vegetation index (NDVI) and the floating algae index (FAI) play an important role in such ...

A contribution to the economic assessment of green tides

, 2016
Provoquées par des efflorescences saisonnières de macro-algues vertes de la famille des ulvacées, les marées vertes appartiennent à la classe plus large des blooms algaux nuisibles (HAB), en rapide développement dans le monde depuis trois décennies, sous l’effet notamment de l’eutrophisation des eaux côtières due aux activités humaines.

An Improved UAV RGB Image Processing Method for Quantitative Remote Sensing of Marine Green Macroalgae

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Red–green–blue (RGB) images (or videos) captured by consumer-level uncrewedaerial vehicle (UAV) cameras are widely used in high-resolution remote observations. However, digital number (DN) values of these RGB images usually have a nonlinear
