摘要
A system and method are provided for optimizing histogram cumulative distribution function curves. In use, a first image is received and divided into two or more pixel regions. For at least one of the two or more pixel regions, a first histogram is computed, and based on the first histogram, at least one cumulative distribution function is computed for the at least one of the two or more pixel regions. Next, based on the at least one cumulative distribution function, two or more curve fit coefficients are extracted and interpolated. Further, an interpolated cumulative distribution function is created based on the interpolation and the interpolated cumulative distribution function is applied to the at least one of the two or more pixel regions.
