Using fractal dimensions for characterizing tortuosity of animal trails

ABSTRACT. The tortuosity of mite trails was characterized by their fractal dimension, which is the non‐Euclidean dimension varying between 1 (completely straight) and 2 (so tortuous that the complete two‐dimensional space is used). This index was shown to be a good, discriminative index for mite trails, which is a completely new use of the fractal dimension. The value of this index is compared with other tortuosity indices.
