Toward omnidirectional and automated imaging system for measuring oceanic whitecap coverage
Accurate measurements of the oceanic whitecap coverage from whitecap images are required for better understanding the air–gas transfer and aerosol production processes. However, this is a challenging task because the whitecap patches are formed immediately after the wave breaks and are spread over a...
