Figure 4From: Extracting complexity waveforms from one-dimensional signalsCircles: fractal dimension ( FD ), as a function of normalized length density (NLD), obtained from a set of Weierstrass functions ( FD = 1.01 – 1.99; γ = 1.1 – 5.0). Solid line: nonlinear fitting with two mathematical models – logarithmic (A) and power (B).Back to article page
