WebIn fractal geometry, the Minkowski–Bouligand dimension, also known as Minkowski dimension or box-counting dimension, is a way of determining the fractal dimension of a set in a Euclidean space , or more generally in a metric space . It is named after the Polish mathematician Hermann Minkowski and the French mathematician Georges Bouligand .
WebBouligand method using exponential dilations M. Luppe The fractal dimension (FD) is an important feature used for classifi-cation and shape recognition. The best method to obtain the FD is the Bouligand-Minkowski method. However, this method is computa-tionally exhaustive because of the use of the distance transform.
