Abstract :
Describes a new approach for positioning boundaries in a discrete image to subpixel values. To correct the position of step edges, the authors combine the operator output and the properties of both operator and edge. This method is simpler to use than existing ones and requires a relatively small amount of computer power. Both availability and reliability are discussed for first and second order operators
