Image-based color palette generation

摘要

A color palette can be a collection of representative colors each associated with a weight or other metadata. A computing system may generate a color palette based on palette generation criteria, which may facilitate or control a palette generation process. Illustratively, the palette generation process may include image pre-processing, color distribution generation, representative color identification, palette candidate generation and palette determination. Representative colors with associated weight can be identified from a distribution of colors depicted by the color image, multiple palette candidates corresponding to the same color image can be generated based on various palette generation criteria, and a color palette can be identified therefrom.

1. A computer-implemented method for generating a color palette, the computer-implemented method comprising:
under control of a hardware computing device configured with specific computer-executable instructions,
obtaining a color image;obtaining a plurality of palette generation criteria applicable to generating a color palette based, at least in part, on the color image, wherein the plurality of palette generation criteria indicate at least one threshold for generating a plurality of palette candidates;generating the plurality of palette candidates corresponding to the color image, wherein each palette candidate of the plurality of palette candidates is generated based, at least in part, on a distinct palette generation criterion of the plurality of palette generation criteria, wherein each palette candidate includes one or more palette colors derived from a plurality of representative colors associated with the color image and wherein the plurality of representative colors are identified from a color distribution corresponding to the color image;generating a color palette in accordance with a selection from the plurality of palette candidates based, at least in part, on an optimization of a relationship between an attribute associated with the plurality of palette candidates to a criterion of the plurality of palette generation criteria; andstoring the color palette in a memory associated with the hardware computing device.
