- property Histogram.cf: ndarray#
Cumulative histogram count values
- Returns:
array of cumulative histogram count values
- Return type:
ndarray(N) or ndarray(N,P)
This the cumulative histogram count, which increases from 0 to the total number of pixels in the image plane.
For a greyscale image this is a 1D array, for a multiplane (color) image this is a 2D array with the cumulative histograms of each plane as columns.
Example:
>>> from machinevisiontoolbox import Image >>> import numpy as np >>> hist = Image.Read('flowers1.png').hist()
Changed in version 2.0.0: In earlier releases this method was named
cdf.
