About

Close-up with overlaid tracked angles onto an original movie. This movie illustrates the methods used in this paper to determine head orientation in bumblebees. The centre of the bee’s head was manually marked by clicking on it in every frame of the sequence. A new image was then generated taking a 90 by 90 pixel sized region around the centre of the head. The image was manually rotated using the computer mouse until it reached the vertical reference direction. The negative value of the angle, which was used to straighten the image, then indicated the yaw orientation of the bee’s head relative to the orientation of the camera.
