Learning faces

Every trout's black spots form a pattern as unique as a fingerprint, and each side of a fish has its own. Watch Old Gravel learn them, live.

1. Find the spotsOnly sharp, close side views of one fish at a time are used. Spot-like points are found on the fish's body, never the rocks.
2. CompareThe spots are compared with every face learned so far. Lines join spots that sit in the same pattern on both photos.
3. DecideSame fish = at least 40 shared spots that line up, and 2.5x more than any other fish. Nothing close = a new face. Anything in between = not sure.
4. Earn a nameA face earns a name after matching on 3 separate visits at least 10 minutes apart. Then it joins The Regulars and Old Gravel names it when it swims by.

Names are Old Gravel's best guess from spot patterns, and a fish's two sides start out as two faces until someone links them. This page as data.
