DragonSearch is a collaborative research project that seeks to expand understanding of wild seadragon populations through meaningful community involvement. Seadragons are icons for marine biodiversity, but there are still many knowledge gaps for their conservation. DragonSearch uses data from underwater imagery to track these unique fish across their distribution for a decade, providing a window into their lives as well as the health of their habitats.

Algorithms
HOTSPOTTER
Hotspotter is a SIFT-based computer vision algorithm. It analyzes the textures in an image to find distinct patterning, or "hot spots", and then compares those against other images in the database. Unlike machine learning-based approaches, HotSpotter can help build new catalogs for new species that need to match individuals but don’t have the training data yet for machine learning-based approaches. Hotspotter can also match new individuals without the need for network retraining. Hotspotter produces a ranked list of potential matches, increasing match scores with increasing similarity.
