Calculation of the animal representation.

(A) Example of the sliding window algorithm for points and with a window size of 5. Contour points with sharp angles are given in red. (B) Animal representation including the notation given in the text. (C) Body bending is calculated based on Eq (3). An animal is not bended if γ = 180°, bended to the left if γ > 180° and bended to the right if γ < 180°.
