This article describes the shape area definition method which is used to specify the closed area with any shape boundary by an interactive pointing device, such as a mouse. By using this method, an operator can specify a simple closed area which has no redundant edge. Whenever the boundary is plotted on the display screen by the pointing device, any unnecessary edge is reduced. This reduction is performed dynamically while an operator is specifying the image area. As a result, the single closed area is automatically defined with one stroke of pen. Because of the generation of the single closed area with no redundant edge, tracing the area is very easy for later processing.
