How can you implement Averaging Technique on Image in Computer Vision?

In the averaging method, it is assumed that you have several images of the same object… each with a different “noise pattern”. This is exactly what can be easily obtained when taking pictures of distant galaxies. The gigantic telescopes just keep looking at the same object. The noise does affect the images, but at the end of the day, you get multiple images of the object with different “noise patterns”… which is exactly what’s needed.

Once you have multiple images, you average them. You take a coordinate, sum up the value at the position in all images. And divide this sum by the total number of images.
