    Abstract: 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 (p i (x,y)) of the starting image respective local homogeneity measures (k(x,y)), and an operation of providing pixel (p 0 (x,y)) of a second digital image by modifying respective pixels (p i (x,y)) of the first digital image on the basis of said respective local homogeneity measures (k(x,y)).

    Abstract translation: 一种用于处理第一数字图像的方法(Q_Impr),包括增加所述数字图像的锐度的操作(A_Sharp)。 该方法的特征在于,增加锐度(A_Sharp)的操作是自适应类型的操作,并且包括将起始图像相应的局部均匀性(TD_Ev)与像素(pi(x,y))相关联的操作 (k(x,y))以及通过基于第一数字图像修改第一数字图像的各个像素(pi(x,y))来提供第二数字图像的像素(p0(x,y))的操作 表示各自的本地均匀性度量(k(x,y))。
