A Chinese Document Image Retrieval Method by Keywords
Pengpeng Wang · Zhongwen xinxi xuebao · 2007
A Chinese document image retrieval method by keywords is proposed,which retrieved Chinese character directly from Chinese character image without OCR(Optical Character Recognition).At first,Chinese character image was segmented from Chinese document image.Then the feature data of Chinese stroke were extracted from the Chinese character image.At last,the similarity of the Chinese character images were measured by weighted modified Hausdorff distance between their feature data.That retrieval method is robust to character size and font.The experimental results show good performance.
