Summary[edit]

Description
English: Measurement of school shape. This movie shows a bounding box around the flock in black. Its dimensions are calculated with the PCA. The shortest dimension is the height. The flock is clearly asymmetrical or oblong. Simultaneously the movie shows the bounding box for measuring the degree to which the flock is elongated in the movement direction (white). (WMV)
