A system and method for selecting an enhancement vector for a plurality of enhancement functions using a cost function. A sharpness enhancement system is described that receives an input picture and outputs an enhanced picture, the sharpness enhancement system comprising: a plurality of enhancement functions that enhance the input picture; and a picture quality analyzer that selects an enhancement vector for the plurality of enhancement functions, wherein the enhancement vector is selected from a set of vectors based on a cost function that comprises: (1) a gradient analysis, and (2) a dynamic range analysis. |
