Reasoning method of unextracted road information on the basis of case-based retrieval mechanism

It is not always easy to correctly extract all of road information about the corresponding road configuration automatically from map images. This is partly because individual map components are not separated explicitly from other map components, and partly because these map components are not necessarily well defined. Thus, it is difficult to overcome these drawbacks by data-driven image processing techniques. Even if model-driven knowledge-based techniques were applied, it is not successful efficiently because the model itself cannot be well specified. In this paper, we address an inference method of unextracted road information on the basis of case-based retrieval mechanism. Our idea is to infer unextracted road information, which could not yet be identified sufficiently by the model-driven knowledge-based approaches, by using case-bases.
