Suppose that you have a 128×128 square pixel image with an 8
gray level intensity range, within which the lighter intensity levels predominate
as shown in the table below. **A)** Sketch the
histogram (number of pixels vs gray level) to describe this distribution.
**B)** How many pixels/gray levels would there be in an equalized version
of this histogram? **C)** Apply the discrete transformation described
above and plot the new (equalized) histogram. (How well does the histogram approximate
a uniform distribution of intensity values?)
