Tracking multiple whiskers in 3D.
A-B) 8 whiskers were tracked in a 3.5 s video sequence (1000 frames/s). C) A sequence of 12 frames showing Bezier curves for all tracked whiskers, projected into horizontal and vertical views, taken from the example video (S1 Movie). Whiskers are colour coded as in panel A. D) Tracking solutions for 2 whiskers (colour coded as in panel A) across 12 frames projected onto horizontal and vertical views. E) 3D tracking solutions for 8 whiskers across a sequence of 30 frames, including the sequence of panel D.
