Digital image processing method for adaptive sharpening

摘要

A method (Q_Impr) for processing a first digital image, comprising an operation (A_Sharp) of increasing the sharpness of said digital image. The method is characterized in that the operation of increasing the sharpness (A_Sharp) is of the adaptive type and includes an operation of associating (TD_Ev) with pixel (pi(x,y)) of the starting image respective local homogeneity measures (k(x,y)), and an operation of providing pixel (p0(x,y)) of a second digital image by modifying respective pixels (pi(x,y)) of the first digital image on the basis of said respective local homogeneity measures (k(x,y)).
