Abstract: This paper proposes a new scale-invariant shape descriptor based on the Multiscale Fractal Dimension (MFD). The MFD is a curve that describes boundary complexity and self-affinity characteristics by obtaining fractal dimension values as function of Euclidean morphologic dilation radii. Using this concept, which guarantees rotation and translation invariance, we introduce a new scale-invariant descriptor that is obtained by selecting a relevant fragment of this curve using a sliding window. The novel shape descriptor is compared with the Multiscale Fractal Dimension and four other shape descriptors. Experimental results demonstrate that the new descriptor is scale-invariant and yields very good results in terms of effectiveness performace when compared with well-known shape descriptors.
