Extraction of character strings from scene image based on feature of color contrast

摘要

In this paper, we propose extraction method of character strings from scene image based on feature of color contrast. To understand condition in scene, characters in scene image are the most important information. Especially, important words are intensified by color scheme compared to other words. This effect is said "color contrast". Therefore we use the feature of color contrast to extract important words. Experimental results show that regions which have strong feature of color contrast intend to include important words. And the results show that character strings in scene image are able to extract from these regions.
