grayscale image as input and returns a length 256 vector h which

is the normalized histogram of the values in the image. h should

Write the function compute_histogram that takes a grayscale image as input and returns a length 256 vector h which is the normalized histogram of the values in the image. h should have values from 0 to 1 and its components should sum to Write the function plot histogram that takes as input a histogram (as returned from compute histogram) and plots it similar to the plots shown below. The x-axis should range from 0 to 255 and be labeled "intensity value". The y-axis should range from 0 to the maximum value of the histogram and should be labeled "PMF" (for probability mass function) a) b)
