摘要：
Captions in digital video are of great importance for video semantic understanding. In order to realize the function of caption detection and positioning, this paper first selects the frames that contain captions then uses the characteristic of edge and projection to locate the caption area in the caption frame. This algorithm avoids the handling of every frame image thus greatly improves the speed of process. By experiments on different kinds of videos, it is demonstrated that the algorithm in this paper has high accuracy.
