Abstract(in English) | In this study, we propose a method extracts dot matrix text used for showing expiration date and manufacturing symbol. The problems of dot matrix text extraction are deformation and rotation by curved surface printing, the difference of the dot arrangement and size of each product and unnecessary characters that are not subject of extraction on the product. In this paper, as a part of the dot matrix text recognition and extraction process, we propose a method for extraction of candidate region of dot matrix text by selecting extracted FAST points using dot characteristics and by clustering of brightness of candidate points. We evaluated performance of the proposed method by experiment with 250 product images. The result shows that recall and precision of text extraction are 94.4% and 40.1%, respectively. |
