Among gestalt principles, the color constancy principle is probably the most basic principle and the easiest to simulate. It states that points with the same color (or gray level) that touch each other are automatically grouped. Since by the Shannon principle an image is a continuous function, we can definitely apply this principle to the level lines of the image, namely the curves along which the gray level u(x, y) is constant.
