“SPLASH scoring” is assigning a numerical score assessing the overall quality of a photo. If a photograph is too blurry or only half the fluke is visible, for example, we use this step to screen it out of the catalog.
“Classifying” photographs is sorting photos according to the pattern of black or white pigmentation on a whale's fluke. This is done to help narrow the photographs used for comparison when matching. Instead of comparing your match photo to all the other photographs in the catalog, you compare it against only those with a similar pigmentation pattern.
“Matching” is a process of comparing fluke photos to see if the same whale has been photographed at a different time and location.
