Of fractal and Fourier: A measure for local shape complexity for neurological applications

Walsh, Erin; Zhang, Tianqi; Cherbuin, Nicolas


Background Local shape complexity can be biologically meaningful as a marker of disease, trauma, or change in brain structure over time. Fractal dimensionality (FD) is currently the dominant measure of local shape complexity used in neuroimaging but its limitations are not well understood. New method Elliptical Fourier harmonic power requirement (HPR) may provide complementary information to FD. We benchmarked the performance of FD and HPR on a series of simulated shapes, systematically...[Show more]
