A description of work-in-progress on PSEIKI is presented. PSEIKI is a computer vision system designed to use multiple sources of knowledge to aid in the image understanding task. In this report we describe the concepts used in PSEIKI and how the incorporation of world knowledge is used to make PSEIKI expectation driven. The world knowledge in the system is represented as a line drawing of the expected scene. The system is implemented as a 2 panel / 6 level blackboard and uses the Dempster-Shafer formalism to accomplish inexact reasoning in a hierarchical space
