Digitization of a real circle is defined as the set of closest pixels (integer lattice points) to the circle. These pixels form a digital circle. First, this paper defines the term “closest pixels” and provides an algorithm to digitize an arbitrary circle, i.e., one whose radius is not necessarily an integer, and whose center is not necessarily a lattice point. This digitizing algorithm is simplified to the case of integer radius and integer-coordinate center so that it can be compared to two… CONTINUE READING
