Abstract
A system and method for improving decisions for 2D combing of a video. A 2D-comb is applied to a baseband video signal, thus producing a chroma component of the signal, and an associated combing error. A narrowband filter is applied to the chroma component to produce a filtered chroma component. The chroma component and the filtered chroma component are blended in proportions based on the amount of combing error to produce a new chroma component. A larger combing error induces selection or blending a larger portion of the filtered chroma component, which as a result of narrowband filtering contains less cross-chroma error. Subtracting the new chroma component from the baseband video signal produces a new luma component. The chroma component can also be filtered using a wider band filter to produce a non-complementary chroma component to be subtracted from the baseband video signal to produce the new luma component.
