Abstract:

This paper presents the development of line following and line analysis pattern recognition routines to automatically computer read hand-drawn logic diagrams. The decision criterion used was based on a tree analysis of segmented lines. The logic diagrams were drawn with a flair pen and the computer program analyzed gates and Flip-Flops within squares ranging from 12 inch to 3 inch in size. All four orientations of the six major logical functions were investigated along with 16 different versions of a J-K Flip-Flop. The output of the program is a series of statements which describe the relationships Gates and Flip-Flops have with each other within a logic diagram. These statements are presented in a form suitable as input statements for a developed Digital Logic Similation program used at the Air Force Institute of Technology. Modified author abstract
