1. A method for encoding pixels of digitized images comprising: providing one or more images comprising a set of image dots, named pixels in two-dimensional images and voxels in three-dimensional images, each of said pixels or voxels being represented by a set of values which correspond to a visual aspect of the pixel on a display screen or in a printed image, characterized in that the pixels ( 5 ) or voxels ( 14 ) of at least one portion of interest of the digital or digitized image or each pixel ( 5 ) or voxel ( 14 ) of the set of pixels or voxels which form the image is uniquely identified with a vector whose components are given by the data of the pixels ( 5 ) or voxels to be encoded ( 14 ) and by the data of at least one or at least some or of all of the pixels ( 1 , 2 , 3 , 4 , 6 , 7 , 8 , 9 ; 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ) around the pixels to be encoded and arranged within a predetermined subset of pixels or voxels included in the whole set of pixels or voxels which form the image.
