Question

Accepted Answer

Histogram equalization is a technique to enhance the contrast of an image by redistributing pixel intensities.

Histogram equalization stretches the histogram of an image to cover the entire range of pixel values.
It increases the dynamic range of an image, making it visually more appealing.
It improves the visibility of details in both dark and bright regions of an image.
Histogram equalization can be used to enhance images with low contrast or uneven lighting conditions.
For example, if an image has a histogram concentrated in the middle range of pixel values, histogram equalization will spread out the histogram to cover the full range of values.
