Software development of the EMI head scanner.
A method has been developed to run the general purpose operating system RDOS on the same disc of the head scanner computer as is used for scanner software and data. This made it possible to develop additional software in high level programming language for image processing, based on original image data on the disc. All new images produced by the program are stored on the disc in the same format as the original images. This makes it possible to handle processed images exactly as the original ones and to do multiple operations. The following processing has been included in the program so far: subtraction, smoothing, density profiles, vertical reconstructions, magnification and labelling. A set of operator commands has been developed which are very similar to the ordinary commands for the scanner, which makes the program to appear being a direct extension of the standard scanner software.
