DEVELOPMENT OF UNMANNED AERIAL VEHICLE (UAV) IMAGE PROCESSING TECHNIQUES FOR MAPPING CORAL REEF

Coral reefs in Malaysian waters were once abundant, but they are now sparse or disrupted due to natural and anthropogenic threats. Reef scientists and managers need a quick and cost-effective solution for assessing and monitoring coral reef habitat degradation. Previous research has shown that advan...
