1. A method for encoding a digital image, the method comprising:
obtaining image data of the digital image, wherein the image data comprises a plurality of image pixels;
selecting a plurality of sample pixels from the plurality of image pixels;
clustering the plurality of sample pixels based on an influence function that is assigned to each of the plurality of sample pixels, to generate a plurality of hue clusters, wherein the influence function assigned to a sample pixel of the plurality of sample pixels is related to a distance from a position of the sample pixel in a three-dimensional hue axis system;
classifying the image pixels to the plurality of the hue clusters; and
assigning hue values of the hue clusters to the plurality of the image pixels.
