Edge enhancement

Edge enhancement is like coloring in the edges of a picture with a marker to make them look darker and more visible.

Imagine you have a drawing of a tree. If you take a marker and color in the edges of the tree's leaves and branches, they will stand out more and look clearer. This is similar to what happens when edge enhancement is applied to a digital image.

Edge enhancement is a technique used in digital image processing to make edges and boundaries between different objects in an image appear sharper and more defined. This is done by boosting the contrast of pixels near the edges of objects, making them appear darker or lighter than the surrounding pixels.

For example, if you have a photo of a person standing in front of a busy background, edge enhancement can be used to make the person stand out more by making the edges of their body more visible and sharp.

Overall, edge enhancement helps to improve the visual quality and clarity of images, making it easier for us to see and understand the objects within them.
