%T A Software Developement Environment for Parallel Image Processing: Implementation techniques and issues %A D. Crookes, Philip J. Morrow, I. McClatchey, T. Rafferty %E Janet Edwards %B Proceedings of WoTUG\-14: Occam and the Transputer\-Current Developments %X A program development environment has been designed for building transputer based image processing systems. The system has two main components: a library of (parallelised) image processing operations, and a graphical user interface. After introducing the user interface, the paper concentrates on the implementation techniques and issues involved in constructing the environment. The main implementation areas considered are: a flexible and highly parameterised library of image processing routines; the provision of a communications shell which utilises the underlying parallelism without the user having to be concerned about it; and the extensibility of the environment by adding new components to the library.
