Abstract

We propose a system helping the blind to get best-before/use-by date of perishable foods. The system consists of a computer, a wireless camera and an earphone. It processes images captured by a user and extracts character regions in the image by using Support Vector Machine (SVM). Processing the regions by Optical Character Recognition (OCR) and the system outputs the best-before/use-by date as synthesized speech.
