| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Quality of a camera-based handwriting pattern acquisition system is analyzed. The system assumes that the camera is mounted around the pen-tip and acquires a frame sequence, where the fine structure of the paper surface, called paper fingerprint, is captured. SURF keypoints extracted from paper fingerprint are used for establishing the correspondence between two consecutive images. By repeating this process for every pairs of consecutive frames, we can obtain a mosaic image which shows the entire image of the reconstructed handwriting pattern. In this paper, we analyze the causes which degrades the quality of the reconstructed handwriting pattern. |
