Webfrom PIL import Image import numpy as np import matplotlib.pyplot as plt import time Then we'll begin our threshold function: def threshold(imageArray): balanceAr = [] newAr = imageArray Above, we define the function, and we specify that we're expecting a parameter, the imageArray. WebThe only difference between these functions is that array_split allows indices_or_sections to be an integer that does not equally divide the axis. For an array of length l that should be split into n sections, it returns l % n sub-arrays of size l//n + 1 and the rest of size l//n. See also split Split array into multiple sub-arrays of equal size.
