Abstract Toward realization of ``writing-life-log'', a camera-based handwriting pattern acquisition system is proposed. The camera is attached around the tip of a popular pen. It captures frame images around the pen tip continuously. Our problem is video-mosaicing of those frame images by perspective registration of consecutive frames. A key idea is to use precise structure of paper surface, called paper fingerprint, for the registration. Specifically, perspective transformation is estimated by using correspondence of SURF feature points extracted on paper surface. Since the precise structure can be captured stably as the SURF feature points from the pen-tip camera, thus it is possible to expect accurate registration of video frames.
