Camera-based handwriting tracking |
摘要 |
A system for processing handwriting that uses an ordinary camera as an image input device. The output of a single camera is used to produce a probability function that indicates the likelihood of whether the pen is touching the paper. The function uses clues including ink on the page and/or shadows. Another embodiment uses both pen up and pen down information to dynamically time warp-fit the information to fit it to a template.</PTEXT> |
