Looking at projected documents: event detection & document identification
Ardhendu Behera, Denis Lalanne, Rolf Ingold · 2005
In the context of a multimodal application, the article proposes an image-based method for bridging the gap between document excerpts and video extracts. The approach, called document image alignment, takes advantage of the observable events related to documents that are visible during meetings. In particular, the article presents a new method for detecting slide changes in slideshows, its evaluation, and a preliminary work on document identification.
