Edge detection is a fundamental tool in image processing, machine vision and computer vision, particularly in the areas of feature detection and feature extraction, which aim at identifying points in a digital image at which the image brightness changes sharply or, more formally, has discontinuities. The same problem of finding discontinuities in 1D signals is known as step detection.

“Dragging out life to the last possible second is not living to the best effect. The nearer the bone, the sweeter the meat. The best of life, Passworthy, lies nearest to the edge of death.”
—H.G. (Herbert George)
