ABSTRACT:
Methods and systems for correlation sharpening filtering of a composite video signal are provided. A correlation between a current pixel and at least one adjacent pixel may be determined. A plurality of chroma video signal components of a composite video signal may be blended based on the determined correlation. A luma video signal component may be determined based on the blended chroma video signal components. At least a portion of the plurality of chroma video signal components may be filtered, resulting in filtered chroma video signals. At least a portion of the plurality of chroma video signal components may be blended with the filtered chroma video signal based on the determined correlation. The blended at least a portion of the plurality of chroma video signal components may be removed from the composite video signal to obtain the luma video signal component.
