Objective Determination of Branching Angles in Fractals J. Phys. I France, Vol. 42.30.Sy - Pattern recognition.
Recognition is performed by correlating the object with V-shaped identifiers.
We define a quantitative criterion to prove the existence of characteristic branching angles in such figures. A neat characteristic angle is found in dendritic aggregates, in agreement with visual impression. However, the procedure does not find any dominant branching angle in basic Witten and Sander aggregates.
