| Summary: | 碩士 === 國立交通大學 === 資訊科學與工程研究所 === 96 === Centerline is one of many methods to describe the shape of objects. The method simplifies and maintains the main structure of objects such as topological characteristics. Therefore, the preference of searching for centerlines in image analysis and pattern recognition is mostly applicable. However, centerline method is not well-defined and consequently causes the difficulties of calculation. The thesis provides a way to search for centerline of objects by integrating gradient vector flow and distance transform. In addition, we apply the method on the images with various figures and the result indicates great match with centerline conditions.
