Google launches cloud-based intelligent video search API
Google has launched Cloud Video Intelligence as a private beta. The service, accessed through either REST API or client libraries, allows developers to search catalogues of video files much as they can currently search text databases, without having to build – or have any knowledge of – machine learning or computer vision.
Use case

Contextual advertisements

You can identify appropriate locations in videos to insert ads that are contextually relevant to the video content. This can be done by matching the timeframe-specific labels of your video content with the content of your advertisements.
