Histogram Equalization

Histogram Equalization is a technique used to improve the contrast of images. It works by redistributing the brightness levels across the entire range, making dark areas lighter and light areas darker. Imagine a graph that shows how often different brightness levels appear in an image—this graph is called a histogram. By adjusting this histogram so that it spreads out more evenly, we can enhance the details in the image, making it clearer and more visually appealing. This process is commonly used in photography and medical imaging to reveal important features that may be difficult to see.
