摘要 |
A method is provided for deriving an objective sharpness metric for objectively determining the level of image sharpness of many and unspecific images having different degrees of sharpness. The method for deriving the objective sharpness metric utilizes sub-band frequency information and false edge information for both an original video sequence and a sharpened sequence to be scored. |
