Brief Abstract:

Coral Reefs are very important for the marine ecosystems and monitoring the coral reefs can be a very difficult task for the marine biologists. Providing a mosaic of the coral reef decreases significantly the labor for the experts while it provides a better and fast way to study better the coral reefs. We use simple and cheep to constract sensors, called Drift-Nodes, that been equipped with minimal cost of sensors (camera, GPS, IMU), they were deployed on the surface, above a coral reef in Barbados, and we used feature detection methods with feature matching to reconstruct a mosaic.
