| Abstract(in English) | Annotations on paper documents include important information, which can be exploited by their extraction and analysis. In this report, we propose a method of annotation extraction from paper documents. In the proposed method, annotations are extracted by comparing a document image of an annotated document captured using a scanner and its original document image. The proposed method is characterized by precise matching and flexible subtraction of images. Experimental results have shown that annotations can be extracted using the proposed method with 76% accuracy in the cases of color documents and 94% accuracy in the cases of monochrome documents. |
