Laplacian Filter

A Laplacian filter is a mathematical tool used in image processing to highlight areas of rapid intensity change, such as edges or boundaries within an image. It works by examining each pixel's brightness in relation to its neighbors, detecting where there are sharp differences. This makes the edges stand out more clearly, helping in tasks like object recognition or image enhancement. Think of it as a way to sharpen the boundaries in a picture, making edges more defined and details more noticeable.
