One method for detecting watermarks from a host content includes performing watermark extraction to obtain a first sequence of watermark symbols from the host content and generating a plurality of predicted watermark templates. Each template corresponds to a sequence of watermark symbols that is predicted based on the first sequence of watermark symbols. A section of the host content is processed to obtain a candidate sequence of watermark symbols and correlation operations between the candidate sequence of watermark symbols and symbols of the predicted watermark templates are performed until a correlation result that is indicative of a successful watermark detection is obtained. An indication that the candidate sequence of watermark symbols represents at least a portion of a reliably extracted watermark message can then be produced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Watermark detection using a multiplicity of predicted patterns","description":"Methods, devices and computer program products allow improved detection of watermarks into and from a multimedia content.
