A geometric point can be defined as a geometric element that has a position but no dimensions and is pictured as a small dot. Although the geometric point is invisible, when using the camera, one can consider a geometric point to be any object that occupies a small compact portion of an image. Even though in simple images it is possible for points to exist as independent elements, most photographs are actually complex, which means that the points will typically coexist with other points, lines and shapes. Under such circumstances, geometric points can exist either as a dominant element or a subordinate one.
