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 first color distance threshold and a second color distance threshold for use in generating a color palette, wherein the color palette is generated based, at least in part, on the color image;identifying a plurality of representative colors and a plurality of color weights based, at least in part, on the color image, wherein identifying the plurality of representative colors and plurality of color weights comprises:
determining a popularity of a group of colors among a plurality of users;selecting a color from a current color distribution corresponding to the color image based, at least in part, on the popularity;identifying a first subset of colors in the current color distribution that have a color distance within the first color distance threshold from the selected color;determining a representative color to be a color representing the identified subset of colors;associating a color weight with the determined representative color based, at least in part, on a collective weight measure corresponding to the identified first subset of colors;identifying a second subset of colors in the current color distribution that have a color distance within the second color distance threshold, from the determined representative color; andgenerating a new color distribution from the current color distribution by removing the second subset of colors from the current color distribution; andgenerating the color palette based, at least in part, on the identified plurality of representative colors and plurality of color weights.
