A VISUAL PROGRAMMING ENVIRONMENT FOR INTERACTIVE DEVELOPMENT OF MACHINE VISION ALGORITHMS FROM REUSABLE IMAGE PROCESSING SOFTWARE COMPONENTS IS DESCRIBED. THIS SYSTEM EMPLOYS A GRAPHICAL EDITOR FOR MANAGEMENT OF THE SYNTAX OF DATAFLOW GRAPHS THAT DESCRIBE THE LOGICAL RELATIONSHIPS BETWEEN COMPONENTS OF SYSTEMS. A POST-PROCESSOR PROVIDES THE SEMANTICS OF OPERATION OF THESE COMPONENTS BY SUPPLYING PRIMITIVE (I.E. LOW-LEVEL) IMAGE PROCESSING PARTS AND AN ENGINE FOR DIRECT EXECUTION OF DATAFLOW GRAPHS. BASED ON AN ENGINEERING DESIGN METAPHOR, THE SYSTEM SUPPORTS TOP-DOWN DESIGN EFFORTS BY ALLOWING EARLY DEFINITION OF HIGH-LEVEL PARTS WHOSE IMPLEMENTATION IN TERMS OF OTHER PARTS MAY BE POSTPONED ARBITRARILY. IN ADDITION, BOTTOM-UP CONSTRUCTION EFFORTS ARE SUPPORTED BY COMBINING EXISTING LOW-LEVEL PARTS INTO LARGER COMPOSITE PARTS THAT MAY BE IMMEDIATELY EXECUTED AND TESTED, CREATING AN EARLY
