Polarization-intensity joint imaging for marine target automatic recognition

open access: yesGeocarto International, 2023
The performance of sole optical imaging device for marine target recognition is degraded by sea fog, sea-glint, and many other disturbing factors. To enhance the ability of target recognition in marine environment, we propose a polarization-intensity ...
