Abstract:
1. A method for optimizing the sharpening of a video sequence using an objective sharpness quality score derived from an objective sharpness metric for determining the sharpness quality level of video sequences having different degrees of sharpness, said method comprising the steps of; receiving as an input an original video sequence; processing the original video sequence to derive a sharpened video sequence; calculating a first spectral energy information in said sharpened video sequence; calculating a second spectral energy information in said original video sequence; calculating false edge information data in said sharpened video sequence; deriving said objective sharpness metric from said first and second spectral energy information and said false edge information, said objective sharpness metric providing said objective sharpness quality score representative of the quality of said sharpened video sequence; and re-processing the original video sequence using said objective sharpness quality score to derive an optimized sharpened video sequence.
