9ix&SSKJr SSKJr SSjrg))unique)entropyc,[USS9up#[X1S9$)a6Calculate the Shannon entropy of an image. The Shannon entropy is defined as S = -sum(pk * log(pk)), where pk are frequency/probability of pixels of value k. Parameters ---------- image : (M, N) ndarray Grayscale input image. base : float, optional The logarithmic base to use. Returns ------- entropy : float Notes ----- The returned value is measured in bits or shannon (Sh) for base=2, natural unit (nat) for base=np.e and hartley (Hart) for base=10.
