METAREASONING IN THE DETERMINATION OF IMAGE INTERPRETATION STRATEGIES

Flexible determination of image interpretation strategies is made possible by reasoning on the state of the interpretation process. The state is here described as a string of attributed symbols denoting images, descriptions, actions and patterns of actions. Goals of the interpretation are specified by Conditional Attributed Rewriting Systems. An interpreter exploits these systems to interpret the image, i.e., to determine the evolution of the state from the initial state to the final interpretation. An example from liver biopsy interpretation is introduced, its results contrasted with those of human interpretations and the automatic interpreter efficacy commented on.
