| Abstract(in English) | The paper proposes a method which extracts Hangul regions and recognizes Hangul alphabets in images captured by a digital camera. The proposed method extracts candidates of Hangul alphabets from edge images by using the feature of Hangul structure. As a subsequent process, based on the Hangul structure and homochromaticity of an identical text, the Hangul regions are extracted by clustering procedure in color space. Texture regions and noise are excluded and Hangul alphabet regions are extracted from edge images by using simplicity of the Hangul structure. The extracted candidates are classified into character regions and background in color space. The clustering process is performed in circumscribed rectangles of extracted edges in the previous procedure. Moreover, the proposed method recognizes the extracted Hangul alphabets which are ideally written. It analyzes endpoints and intersected points of the extracted alphabet skeletons. The proposed method extracts 85.97% of Hangul text from 100 images captured on arbitrary conditions. Furthermore, 71.96% of alphabets are recognized for ideal Hangul of which Hangul alphabets are not connected each other in a character. |
