Camera-Based Whiteboard Reading for Understanding Mind Maps

A Method for Camera-Based Interactive Whiteboard Reading

Recognizing mind maps written on a whiteboard is a challenging task due to the unconstrained handwritten text and the different graphical elements — i.e. lines, circles and arrows — available in a mind map. In this paper we propose a prototype system to recognize and visualize such mind maps written on whiteboards. After the image acquisition by a camera, a binarization process is performed, an...

Camera-Based Whiteboard Reading: New Approaches to a Challenging Task

We suggest a system for recognizing handwriting text from a whiteboard. In contrast to the mainstream approaches, we are able to recognize text solely from still images and do not require additional hardware or tracking of the writer’s hand. The proposed system contains extraction of text areas, suitable image preprocessing steps, line extraction, and finally text recognition. Since we are deal...

Layout Analysis for Camera-Based Whiteboard Notes

A domain where, even in the era of electronic document processing, handwriting is still widely used is note-taking on a whiteboard. Such documents are either captured by a pen-tracking device or – which is much more challenging – by a camera. In both cases the layout analysis of realistic whiteboard notes is an open research problem. In this paper we propose a camera-based three-stage approach ...

Towards Automatic Video-based Whiteboard Reading

As whiteboards have become a popular tool in meeting rooms, there has been a growing interest in making use of the whiteboard as a user interface for human computer interaction. Therefore, systems based on electronic whiteboards have been developed in order to serve as meeting assistants for e.g. collaborative working. However, as special pens and erasers are required, the natural interaction i...
