| Abstract(in English) | A dot-matrix character is a character formed by a dot matrix and used in such factory automation application as product quality management. If the machine can automatically recognize dot-matrix characters it will contribute greatly to the industry applications from the viewpoints of cost, operational aspects, etc. In the task of character recognition, it is common to generate an input image for individual characters, so image segmentation into each character region is necessary. However, such existing approaches relying on pixel connectivities cannot be used for dot-matrix characters. In this research, we propose a top-down segmentation method which gradually narrows down dot-matrix character regions considering such characteristics. In this research, we evaluated the proposed segmentation method with a variety of images containing printed dot-matrix characters including difficult properties such as distortion and specular highlights which have not been verified in existing studies. |
