Web26 Oct 2024 · To determine the histogram of an image, we need to count how many instances of each intensity we have. So, a histogram will allow us to see how often each intensity occurs. In our example, the intensity 150 can be seen in three pixels, for this reason, it will have a higher frequency in the histogram (the corresponding bar’s height is 3): 3.
