Abstract
A method for modifying an image being defined by a matrix of pixels comprises: •calculating (1) a color frequency distribution of the matrix of pixels; •defining (3) for each pixel an energy value as a weighted function of the color frequency of the pixel, so as to define an image saliency map; •transforming (5) the image, said transformation being based on the pixel energy values. A computer software product to apply the method, an apparatus and a TV set are also disclosed.
