THIS PAPER PROVIDES AN OVERVIEW OF THE IMAGE UNDERSTANDING ARCHITECTURE (IUA), A MASSIVELY PARALLEL, MULTI-LEVEL SYSTEM FOR SUPPORTING REAL-TIME IMAGE UNDERSTANDING APPLICATIONS AND RESEARCH IN KNOWLEDGE-BASED COMPUTER VISION. THE DESIGN OF THE IUA IS MOTIVATED BY CONSIDERING THE ARCHITECTURAL REQUIREMENTS FOR INTEGRATED REAL-TIME VISION IN TERMS OF THE TYPE OF PRO- CESSING ELEMENTS, CONTROL OF PROCESSING, AND COMMUNICATION BETWEEN PROCES- SING ELEMENTS. THE IUA INTEGRATES PARALLEL PROCESSORS OPERATING SIMULTANEOUSLY AT THREE LEVELS OF COMPUTATIONAL GRANULARITY IN A TIGHTLY-COUPLED ARCHITECTURE. EACH LEVEL OF THE IUA IS A PARALLEL PROCESSOR THAT IS DISTINCTLY DIFFERENT FROM THE OTHER TWO LEVELS, IN ORDER TO BEST MEET THE PROCESSING NEEDS AT EACH OF THE CORRESPONDING LEVELS OF ABSTRACTION IN THE INTERPRETATION PROCESS. COM- MUNICATION BETWEEN LEVELS TAKS PLACE VIA PARALLEL DATA AND CONTROL PATHS. THE PROCESSING ELEMENTS WITHIN EACH LEVEL CAN ALSO COMMUNICATE WITH EACH OTHER IN PARALLEL, VIA A DIFFERENT MECHANISM AT EACH LEVEL THAT IS DESIGNED TO MEET THE SPECIFIC COMMUNICATION NEEDS OF EACH LEVEL OF ABSTRACTION. AN ASSOCIATIVE PROCESSING PARADIGM, THAT PROVIDES A SIMPLE YET GENERAL MEANS OF MANAGING MASSIVE PARALLELISM, HAS BEEN UTILIZED AS THE PRINCIPLE CONTROL MECHANISM AT THE LOW AND INTERMEDIATE LEVELS. CONTROL OF PROCESSING IN THESE LEVELS IS BASED UPON THEIR RAPID RESPONSES TO QUERIES, INVOLVING
