PROBLEM TO BE SOLVED: To provide a picture processing method of precisely extracting only the outline of a graphic (object) with a simple processing and of precisely calculating the peripheral length of the object. SOLUTION: A picture processing for extracting only the outline M from the picture of the object is executed in the method. The respective picture elements of the picture are binarized with arbitrary brightness and the value and position of the arbitrary binarized picture element are defined as Pij , the values and the positions of four upper/lower/right/left picture elements adjacent to the picture element Pij are defined as Pij-1 , P1-1j , Pi+1j and Pij+1 . Then, the picture element Pij and the adjacent picture elements are processed by Boolean algebra and the processing is executed on all the picture elements. Thus, only the outline M of the object is extracted. |
