How does video retrieval work?
Content-based Video Retrieval refers to the provision of search facilities over archives of digital video content, where these search facilities are based on the outcome of an analysis of digital video content to extract indexable data for the search process.
What is semantic gap in image processing?

What is video indexing and retrieval?
