Development of a Semi-automated Coral Bleaching Classifier in CoralNet: A Summary of Standard Operating Procedures and Report of Results

October 31, 2022

Steps and skills that can be utilized to produce the good image quality that is essential for annotating imagery in CoralNet.

In this report, we provide a description of how to create a coral bleaching classifier in CoralNet
using photoquadrat imagery. We also include a summary of accuracy of NOAA ESD’s classifier
at both the point and site level. The trained bleaching classifier is publically available (Global ID
24223) and can be accessed using the CoralNet Application Program Interface (API). See the
API blog (https://coralnet.ucsd.edu/pages/help/api/) for details.

The Pacific Islands Fisheries Science Center of NOAA’s National Marine Fisheries Service uses
the NOAA Technical Memorandum NMFS-PIFSC series to disseminate scientific and technical
information that has been scientifically reviewed and edited. Documents within this series reflect
sound professional work and may be referenced in the formal scientific and technical literature.
