edges

Edges are the boundaries or lines where different parts of a shape, object, or image meet. In images, edges help define the outline of objects, making it easier to distinguish one item from another. They are also present in natural features like mountain ridges or the edges of landforms. Detecting edges is important in computer vision and image processing because it helps systems understand the structure and features of visual information, enabling tasks like recognition, segmentation, and analysis. Think of edges as the visual "lines" that help us see where one thing ends and another begins.
