Abstract |
We are developing an Automatic Camera control system for Education: ACE, which captures a traditional lecture. ACE focuses on the latest object that a teacher writes on a blackboard. When this recordi...ng strategy is realized, it is necessary for ACE to detect beginning and ending of the teacher’s writing. The early version of ACE mis-judges ending of his writing according to the region occluded by a teacher because it detects the region only using image processing. In this paper, we describe a method of detecting the beginning and ending with both image and sound processing. We have applied our method to recording a real lecture to validate it.show more
