Abstract

PURPOSE:To express a recessed right angle part as a clear right angle by deciding an angle as the recessed right angle part when a certain chain code group is a constant pattern, adding the chain code and changing the chain code group. CONSTITUTION:The chain code advances to '...007' in a horizontal part to reach a corner picture element (a), and thereafter, moves to a vertical part to advance to '66...'. The chain code is '076' and when this combination is generated in a chain code string, it is immediately decided to be the recessed right angle part opening to a left downward part. Herein, a change is applied to the chain code to change the last picture element (c) of the horizontal part to '6' so as to include the corner picture element (a) and further the chain code '6' is applied to the corner picture element (a). This corresponds to an operation for changing the set of the chain code '076' to '0066'.
