Abstract

This paper deals with the hardware design of a real-time image preprocessor to service the operation of the DIAS system. DIAS is an autonomous, multiprocessor picture information system consisting of four hierarchical levels of operation (Master Planning, Distributed Service Control, Execution and Backend). The pre-processor proposed here receives parallel image data from the environment and provides to DIAS Master-Planner-Processor a number of image features (parameters) in order to service the decision making about the input image. These image features are: size (number of pixels); type (binary, or grey level picture); total average intensity of the picture; uniformity of the picture; number of informative square areas and their size; geographical locations of the informative picture regions and their grey level averages.
