摘要:Whiteboards have been very popular in corporate sectors and in educational institutions because of its usefulness and contribution towards modern day corporate life. Besides traditional whiteboards, digital whiteboards have been developed in the recent past, which acts as a bridge for interaction between human and computer. Despite its usefulness digital whiteboards have some drawbacks also, like the requirements of specialized pens and erasers so that’s why systems have been developed to capture contents from traditional whiteboards, thereby supporting the efforts to use traditional whiteboards. We have targeted educational sector for our research work. We have designed a system for capturing the content on whiteboard and produce handouts using a digital camera. Our video analytic algorithm captures video lectures, detects and tracks the instructor movement to overcome the problem of instructor occlusion, extracts the whiteboard region, scans the whiteboard for text extraction and finally generates the lecture handouts on the decision of erasing the whiteboard.
