Towards automatic video-based whiteboard reading

摘要: As whiteboards have become a popular tool in meeting rooms, there has been growing interest making use of the whiteboard as user interface for human computer interaction. Therefore, systems based on electronic developed order to serve assistants e.g. collaborative working. However, special pens and erasers are required, natural interaction is restricted. In render this communication method more it was proposed retain ordinary visually observe writing process using video camera by Stafford-Fraser Robinson (1996). paper prototype system automatic video-based reading presented. The designed recognizing unconstrained handwritten text further characterized an incremental processing strategy facilitate portions soon they written board. We present methods employed extracting regions, pre-processing, feature extraction, statistical modeling recognition. Evaluation results writer independent handwriting recognition task demonstrate feasibility approach.
