In mathematics, this is equivalent to calculating the integral of the histogram between the points $a$ and $b$ ; this is the reason for which the cumulated histogram is also called ” histogram integral “.
This function calculates also the cumulated histogram (file CUMUL.DAT) and the opposite cumulated histogram (file CUMUL_INV.DAT).
The advantage of the cumulated histogram is that it allows you to calculate very easily the number of pixels having a value between two gray levels given $a$ and $b$ simply to calculate the difference $h_b^c – h_a^c$ .
