Human Supervisory Control Framework for Interactive Medical Image Segmentation
In this work, interactive segmentation is integrated with an active contour model, and segmentation is posed as a human-supervisory-control problem. User input is tightly coupled with an automatic segmentation algorithm leveraging the user’s high-level anatomical knowledge and the automated method’s speed. Real-time visualization enables the user to quickly identify and correct the result in a subdomain where the variational model’s statistical assumptions do not agree with his expert knowledge. Methods developed in this work are applied to magnetic resonance imaging (MRI) volumes as part of a population study of human skeletal development. Segmentation time is reduced by approximately five times over similarly accurate manual segmentation of large bone structures.
