Histogram matching principle is not much to explain, I have also been the MATLAB source rewrite into the C source code, the details can be seen in accordance with the MATLAB Histeq function rewritten under the OPENCV of the histogram prescribed C source code! The following directly to the source code and run the results: The source of the desired picture download link is:Coins.png Http://pan.baidu.com/s/1

I do not intend to elaborate on professional terms, and interested readers can refer to the reference link at the end of the article, where there are understandable explanations: Let's look at an example image (taken with Canon 550D): Example Picture: butterfly.jpg Here's how to implement the image histogram using Imagick: Copy Code code as follows: $file = ' butterfly.jpg '; $size = Array

People who have played SLR cameras should know the image histogram (ImageHistogram). Simply put, it calculates the proportion of each color level in the total pixel to reflect the image exposure. I am not going to explain the terms in detail. if you are interested, you can refer to the reference link at the end of the article. there are easy-to-understand explanations: Let's first look for an example image (shot with

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 and provides a foreshadowing for understanding the connotation of various spatial enhancement techniques.

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 number of pixels in the gray-level image (or the occurrence frequency of these pixels, the ordinate represents the number (frequency) of gray-level occurrences in

This paper mainly discusses histogram equalization , histogram stipulation (matching), Local histogram , constrained contrast adaptive histogram equalization (CLAHE), and image enhancement based on histogram statistics. 1. Histogram
