Abstract
Image processing systems based on general purpose processors and raster-scan image I/O devices are limited in efficiency and flexibility by te nature of their component devices. These limitations may be traced to three aspects of the system: the nature of the scan operation, the complements of I/O and arithmetic/logic instructions, and the management of data storage resources. A fixed, raster scan is often undesirable in that it imposes a directionality on image data which is not a property of the image itself. It is also inefficient from the viewpoint of maximizing the rate of convergence of sequential estimation schemes. A general purpose instruction set is poorly suited to image processing in that basic I/O and artihmetic macro-operations such as scan line access or digital filter operations require long stirngs of machine code. Finally, data management schemes in most operating systems are poorly suited to the establishment and access of large, two-dimensional data files.
