Tracking plots involved in maneuver detection. a: Segments of a sailing maneuver. (1) Sailors stable on left side, (2) crossing the middle of the boat, and (3) stable on the right side; b: Regression line before zero crossing. Orange line is the output of the (too) coarsely filtered calculated difference; c: Adaptation to frames using edge focusing signature graph at different values of σ, allowing tracking from coarse to fine
