Histogram is an important basic tool in digital image processing, before we discuss various spatial image processing, we must first understand the concept of histogram and its meaning.
The histogram provides the statistical information of the image
Grayscale histogram is the simplest and most useful tool for digital images. This article mainly summarizes the structure and application of cvhistogram in opencv.The definition of a grayscale histogram is a gray-level function that describes the
This paper mainly discusses histogram equalization , histogram stipulation (matching), Local histogram , constrained contrast adaptive histogram equalization (CLAHE), and image enhancement based on histogram statistics.

Preface
Histogram is a very important tool in computer vision. opencv provides many functions related to histogram processing. The most basic function is to calculate the histogram function calchist (). The histogram is also introduced in the

I. Concepts of image histograms
The image histogram is a statistical table that reflects the Pixel Distribution of an image. In fact, the abscissa represents the type of the image pixel, which can be gray or color. The ordinate represents the total
The gray histogram of digital image is described earlier, and the application of histogram is now tried. Histogram equalization
Histogram equalization (histogram equalization) is the most typical application of histogram, which is a kind of image
