Introduction to Continuous Image Histograms

In this lecture we introduce the concept of a continuous histogram. That is, a histogram that is a continuous function of image intensity, and we'll illustrate the integral and derivative relationships between the normalized histogram -- or frequency histogram -- and the cumulative frequency distribution. Although the intensities for all real images are restricted to a finite set of possible values, the continuous histogram is an important mathematical tool that enables us to derive some useful intensity transformations for image enhancement.

Very well spoken and easy to follow. I really appreciate the basic examples. Thank you.
