| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a method for character string extraction from scene images using direction distribution of edge components and their spatial arrangements. First, we detect edge components using Canny operator as applied to individual RGB channels. Second, we extract character strings based on spatial arrangements of edge components. Third, we extract isolated characters using direction distribution features of edge components. Finally, we extract concatenated characters based on tentative segmentation into character-like components and evaluation of character likeness. Experimental results made on a total of 249 images extracted from ICDAR2003 dataset show that the proposed method achieves a recall rate of $67.6\%$, a precision rate of $62.9\%$, and a F measure of $65.1\%$. | |
