how to generate abstract for a video?

Question

Hello everyone,

For a video file (e.g. wmv file or other format), I need to generate abstract for the video. The abstract is expected to be in text format. Any mature tools or algorithms? Better (not a must) if open source tools/SDKs so that I can modify for my special needs.

thanks in advance, George

Answer 1

If I understand 'abstract' correctly, you should look into Hachoir-Metadata, see their example page:

Answer 2

If you're looking for a textual description of a video's content given only the video's frames, then I'm afraid you're out of luck -- the current state of computer vision research is well short of that goal. If you can settle for a non-textual description, video keyframe or shot/scene detection algorithms can give you an image-based summary.
