The signatures are calculated, formed into data structures and organized in a database for quick searching and matching operations used in content recognition. For content recognition, signals are sampled and transformed into signatures using the multi axis filter. The database is searched to recognize the signals as part of a content item in the database. Using the content identification, content metadata is retrieved and provided for a variety of applications. In one application, the metadata is provided in response to a content identification request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robust signatures derived from local nonlinear filters","description":"Content signal recognition is based on a multi-axis filtering of the content signal.
