A System to Acquire Expiration Date of Merchandise for Visually Impaired People -- a discussion about improvement of recognition rate with machine learning --
Takeuchi Yoshinori (Daido Univ.) WIT2019-13
Abstract (in Japanese) (See Japanese page) 
(in English) We have been researching a system to acquire expiration date of Merchandise for visually impaired people. In this paper, we aim to improve the recognition rate of the conventional expiration date acquisition system by machine learning technology. In order to limit the printed part of expiration date, characters of “kigen(期限)” or “gen(限)” are learned by machine learning, and we compare the recognition results. Compared with 78.6% recognition rate in the conventional method that used SVM for recognition, the recognition rate of “kigen(期限)” for the images taken from the front was 84% and the recognition rate of “gen(限)” from the images taken for various angles was 78.9%. The recognition rate of expiration date was 40% in conventional method that used a commercially available OCR library, whereas it was 100% for the images taken from the front and 40% for the images taken from various angles.
