Abstract
A system and method for encoding a digital image may include 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 to generate a plurality of hue clusters, 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.
Claims22
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.
A system for encoding a digital image, the system comprising:
- a memory;
- a processor configured to:
- obtain image data of the digital image, wherein the image data comprises a plurality of image pixels;
- select a plurality of sample pixels from the plurality of image pixels;
- cluster 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;
- classify the image pixels to the plurality of the hue clusters;
- and
- assign hue values of the hue clusters to the plurality of the image pixels.
