- * Fish Detector Hook
- * Copyright (c) 2002 Philip Gladstone
- *
- * This file implements a fish detector. It is used to see when a
- * goldfish passes in front of the camera. It does this by counting
- * the number of input pixels that fall within a particular HSV
- * range.
- *
- * It takes a multitude of arguments:
- *
- * -h <num>-<num> the range of H values that are fish
- * -s <num>-<num> the range of S values that are fish
- * -v <num>-<num> the range of V values that are fish
- * -z zap all non-fish values to black
- * -l <num> limit the number of saved files to <num>
- * -i <num> only check frames every <num> seconds
- * -t <num> the threshold for the amount of fish pixels (range 0-1)
- * -d turn debugging on
- * -D <directory> where to put the fish images
