ABSTRACT

Most of the existing character region extraction methods have focused on 2D character regions in video. However, there are also a lot of atypical characters in video and natural images, and they often have significant meanings. In this paper, we propose a method to extract atypical character regions using a graph theory. We first perform a preprocessing for character extraction and segments each region. We then obtains atypical character regions from segmented regions by using a graph algorithm. Experimental results show that the suggested system extracts atypical characters effectively.
