Abstract

This disclosure related to systems and methods of palette-based color editing. A set of principle colors may be identified from among individual colors of individual pixels of an image. Color distributions about the individual principle colors may be determined. An individual color distribution may include a homogenous range of colors that may vary with respect to an individual principle color. Pixels may be associated with one or more pixel groups based on correspondences between individual colors of the individual pixels and individual colors included in the individual color distributions corresponding to the individual pixel groups. Color editing may be effectuated by modifying colors of pixels in a given group independently from other colors of other pixels in other groups.

Claims20

Dependent claims

A system configured to facilitate palette-based color editing, the system comprising:

non-transitory electronic storage storing visual information of a first image, the visual information defining individual colors of individual pixels of the first image;
and
one or more physical processors configured by machine-readable instructions to:
identify a set of principle colors from among the individual colors of the individual pixels of the first image;
determine color distributions about the individual principle colors, an individual color distribution including colors that vary with respect to an individual principle color, such that:
responsive to identifying a first principle color of the first image, a first color distribution about the first principle color is determined, the first color distribution including a first set of colors that vary with respect to the first principle color;
and
responsive to identifying a second principle color of the first image, a second color distribution about the second principle color is determined, the second color distribution including a second set of colors that vary with respect to the second principle color;
and
determine pixel groups by associating individual pixels with one or more of the pixel groups, individual pixel groups corresponding to individual color distributions, wherein individual pixels are associated with one or more of the individual pixel groups based on correspondences between individual colors of the individual pixels and individual colors included in the individual color distributions corresponding to the individual pixel groups, the pixel groups including:
a first pixel group corresponding to the first color distribution, a first pixel being associated with the first pixel group based on a correspondence between a first color of the first pixel and a second color within the first set of colors included in the first color distribution;
and
a second pixel group corresponding to the second color distribution, a second pixel being associated with the second pixel group based on a correspondence between a third color of the second pixel and a fourth color within the second set of colors included in the second color distribution.

A method of facilitating palette-based color editing, the method being implemented in a computer system comprising one or more physical processors and storage media storing machine-readable instructions, the method comprising:

storing visual information of a first image, the visual information defining individual colors of individual pixels of the first image;
identifying a set of principle colors from among the individual colors of the individual pixels of the first image;
determining color distributions about the individual principle colors, an individual color distribution including colors that vary with respect to an individual principle color, including:
responsive to identifying a first principle color of the first image, determining a first color distribution about the first principle color, the first color distribution including a first set of colors that vary with respect to the first principle color;
and
responsive to identifying a second principle color of the first image, determining a second color distribution about the second principle color, the second color distribution including a second set of colors that vary with respect to the second principle color;
and
determining pixel groups by associating individual pixels with one or more of the pixel groups, individual pixel groups corresponding to individual color distributions, wherein individual pixels are associated with one or more of the individual pixel groups based on correspondences between individual colors of the individual pixels and individual colors included in the individual color distributions corresponding to the individual pixel groups, the pixel groups including:
a first pixel group corresponding to the first color distribution, a first pixel being associated with the first pixel group based on a correspondence between a first color of the first pixel and a second color within the first set of colors included in the first color distribution;
and
a second pixel group corresponding to the second color distribution, a second pixel being associated with the second pixel group based on a correspondence between a third color of the second pixel and a fourth color within the second set of colors included in the second color distribution.
