Zhi Wan · Jiguang zazhi · 2015
This paper proposes the automatic template extraction algorithm based on OMR. The algorithm is mainly to find representatives of options scribbling area of fuzzy sets by converting real symmetric matrix into diagonal matrix. After extraction of fuzzy sets,we apply OTSU method in mark recognition. By positioning OMR card Identification mark and scribbling marker,we can achieve standardization batch of cards judgment. Application of the proposed method can easily be realized the automatic scoring system and high adaptability.
