WebJan 10, 2013 · Theory. The histogram of a digital image with gray levels in the range [0, L-1] is a discrete function h (rk) = nk, where rk is the kth gray level and nk is the number of pixels in the image having gray level rk. For an 8-bit grayscale image there are 256 different possible intensities, and so the histogram will graphically display 256 numbers ... WebThe histogram function, as the name suggests, computes the histogram of an array of integers, i.e. counts how many instances of each integer are in input_array, and writes the count in output_array. We can now generate some data and run the code.
