Abstract : During the past three months work has been concentrated on two topics, namely the implementation of a framework that allows the integration and test of the system components, and the implementation of low level processing methods. These activities are explained to some detail in the following. Knowledge-based image analysis systems operating on natural images tend to be large software systems, consisting of a multitude of different software components. Therefore, we introduce software engineering methods and some standardizations in software development in order to keep the overall system development under control. Parallel to the implementation of the framework we have begun with the implementation of low level processing methods. Here we use in part methods which have already been developed in the context of other projects.
