| Efficient indexing and retrieval of digital
video is an impor-tant aspect of video databases. One powerful
index for retrieval is the text appearing in them. It enables
content-based browsing. We present our methods for automatic
seg-mentation and recognition of text in digital videos. The
algorithms we propose make use of typical characteristics of text
in videos in order to enable and enhance segmentation and
recognition performance. Especially the inter-frame dependencies
of the characters provide new possibilities for their refinement.
Then, a straightforward indexing and retrieval scheme is
introduced. It is used in the experiments to demonstrate that the
proposed text segmentation and text recognition algorithms are
suitable for indexing and retrieval of relevant video scenes in
and from a video data-base. Our experimental results are very
encouraging and suggest that these algorithms can be used in
video retrieval applications as well as to recognize higher
semantics in video. |
