Ridge detection is like finding the lines on your finger! You know how your fingers have lines running along them? Those are called ridges. Ridge detection is when we look at an image and try to find similar lines or ridges.
So, let's say you have a picture of a mountain range. Ridge detection would help us find the lines in the image that represent the ridge of the mountain range.
It's like playing a game of "connect the dots." We connect dots that are close together and in a line to make a complete line or ridge.
Ridge detection is important because it helps us understand the structure and shapes of objects in an image. It can also be used in computer vision to help machines "see" and understand images.
