uniqueness for each photo being analyzed is given by the date of the sighting and a
key code generated in the database. The process take a several minutes to complete
for each new photograph, depending on the experience of the operator. However for
each new whale to be compared the interpretation of the pattern by the operator is
made only once. As more experienced the operator, the better the potential of the
system.
Other software have been developed, incorporating photos from different perspectives. One is called DIGITS (Digital Image Gathering and Information Tracking
System), developed by the New England Aquarium (http://rwcatalog.neaq.org) to
incorporate imagens of North Atlantic right whales. DIGITS is a data management
system designed to accommodate aerial and shipboard images, providing a platform
to include images from different angles of a right whale (Fig. 16.14). The software
rely on a detailed coding system, rather than an automated interpretation of the
image as the Hiby and lovel (2001) system, to allow for whale-matching searches
Fig. 16.12 The “Right Whale Photo-identification Software” (Hiby and Lovell 2001) use a threedimensional surface model on the head of right whales. The orientation and scaling of the model
to a whale photograph taken from distinct angles is made by identifying four reference points
marked in green and red on this figure
