One of those concepts is histograms. Since understanding histograms is essential to understanding most of the video analysis topics, we'll go through quite a bit of information about them in this section, before moving on to the next topics. A histogram is often referred to as a way of representing the distribution of data. It is a very simple and complete description, but let's also describe what it means in terms of computer vision.
