A plurality of weighting factors corresponding to the reference pixels are determined utilizing non-local means. Chroma components and/or luma components for the current pixel are determined based on weighted least squares utilizing the reference pixels, the weighting factors and information known about the composite signal, for example, sub carrier information. The composite video signal may comprise baseband Y and modulated Cb and/or Cr components. Weighting factors are determined by comparing a block of pixels about the current pixel with a block of pixels about the corresponding reference pixels in a current, previous or future frame. A set of equations comprising reference pixel data, a set of weighting factors and/or the known information may be solved to the determine signal components."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for utilizing non-local means (NLM) for separation of luma (Y) and chroma (CbCr) components","description":"One or more processors and/or circuits receive a composite video signal and determine a current pixel and a plurality of reference pixels.
