In the process of analyzing images, objects and video information, we often use histograms to represent the objects we see. Histograms can be used to describe various things, such as the color distribution of objects, the gradient template of object edges, and the probability distribution of target positions. Histogram is widely used in computer vision applications. In short, histogram is to make statistics on data and organize the statistical values into a series of pre-defined bin. The values in bin are the statistics calculated from the data. These data can be such as gradient, direction, color or any other features. Histogram is the statistical chart of data distribution.
