An interactive image processing system was set up to provide easy use of standard methods and their rapid execution. Point operations and linear and non-linear neighborhood operations were implemented on the display system for integer valued images and on the host for their floating point representation. Fourier domain processing was accelerated by using the refresh memories for auxiliary direct access storage and by computing the EFT with assembly coded routines. Topological operations for segmentation of binary images are done in the display system. Image classification with instant display of the results equally relies on the display hardware. A command processor parses input to verify and validate commands and to separate them from (optional) parameters specified by the user if given default values are not suitable. Usage and integration of image processing procedures is facilitated by maintaining all command language features of the host operating system. Command strings can be set up to repeat sequences of processing steps. A help facility serves to inform the less experienced user.
