Visual Knowledge Representation and Intelligent Image Segmentation

<正> Automatic medical image analysis shows that image segmentation is a crucial task for any practicalAI system in this field. On the basis of evaluation of the existing segmentation methods, a new imagesegmentation method is presented. To seek the perfect solution to knowledge representation in low levelmachine vision, a new knowledge representation approach—— "Notebook" approach is proposed andthe processing of visual knowledge is discussed at all levels. To integrate the computer vision theorywith Gestalt psychology and knowledge engineering, a new integrated method for intelligent imagesegmentation of sonargraphs —— "Generalized pattern guided segmentation" is proposed. With the meth-ods and techniques mentioned above, the medical diagnosis export system for sonargraphs can be built.The work on the preliminary experiments is also introduced.
