Distributed Web-based image processing tool

Image processing performed by non-programmers is greatly simplified by visual programming. We present in this paper an e-service for image processing which requires a new visual programming architecture. This architecture is based on image processing servers and an image data base. The user requires only a web-browser to have access to this service. Time critical image processing code running on the server. is written in a compiled language whereas control tasks are implemented in Python in order to have maximum flexibility. The client side code is written bl Java and JPython br order to be integrated in a web-browser. The application related to this e-service is telepathology,where a domain expert in pathology carl use customized image processing routines made available over the internet in order to extract useful parameters from histological sections.
