What is histogram equalization explain with example?

Histogram Equalization is a computer image processing technique used to improve contrast in images . It accomplishes this by effectively spreading out the most frequent intensity values, i.e. stretching out the intensity range of the image.

What is histogram equalization Geeksforgeeks?

Histogram equalization is a method in image processing of contrast adjustment using the image's histogram. This method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values.

What are the steps of histogram equalization?

Histogram equalization can be done in three steps [1]: Compute the histogram of the image. Calculate the normalized sum of histogram. Transform the input image to an output image.

Which technique is used for histogram equalization?

Histogram equalization is one of the Pixel brightness transformations techniques. It is a well-known contrast enhancement technique due to its performance on almost all types of image.
