Abstract

Systems and methods for color space mapping are disclosed. First image data is received comprising first color information in a first color space, which can be a pixel-based color space. Second image data is generated based on the first image data, comprising converted second color information in a second color space based on the first color information. The second color space can be a pigment-based color space. The second image data is modified in the second color space using at least the converted second color information. Supplemental color data is generated based on the modified second image data. A modified image is generated in the first color space using the modified second image data and the generated supplemental color data, the modified image comprising modified color information in the first color space based at least in part on the supplemental color data. The second image data and the supplemental color data are generated using machine learning.

Background

FIELD

Described embodiments relate generally to color space mapping. BACKGROUND

A digital image comprises visual elements (e.g., pixels) having various characteristics. Characteristics of visual elements can be represented numerically, such as color, intensity, or gray level. Digital images can be associated with various types, such as vector or raster type. Digital images can include photographs, such as unprocessed data captured using an image sensor of a digital camera. Digital images can be edited or manipulated in various ways. Color characteristics of digital image elements are represented using color values based on various color spaces. SUMMARY

The following Summary is for illustrative purposes only and does not limit the scope of the technology disclosed in this document.

In an example embodiment, a method of generating modified images in a first color space is disclosed. First image data is received comprising first color information in a first color space. The first color space can be a pixel-based color space, and the first image data can comprise a digital photograph. Second image data is generated using the first image data, the second image data including converted second color information in a second color space based on the first color information. The second color space can be a pigment-based color space. Multiple color values in the second color space correlate to a same corresponding color value in the first color space. Generat

Claims

1. A computer-implemented method of color space mapping, the method comprising: receiving pixel-based image data comprising pixel color information in a pixel-based color space; generating, using the pixel-based image data, pigment-based image data, wherein the pigment-based image data comprises converted pigment color information in a pigment-based color space based on the pixel color information, wherein generating the pigment-based image data includes generating supplemental color data; modifying the pigment-based image data in the pigment-based color space using at least the converted pigment color information; and generating a modified pixel-based image using the modified pigment-based image data and the generated supplemental color data, wherein the modified pixel-based image comprises modified color information in the pixel-based color space based at least in part on the supplemental color data. || 9. A non-transitory computer-readable medium carrying instructions that, when executed by a processor, cause the processor to perform operations comprising: receive first image data comprising first color information in a first color space; generate, using the first image data, second image data, wherein the second image data comprises converted second color information in a second color space based on the first color information, wherein multiple color values in the second color space correlate to a same corresponding color value in the first color space, and wherein generating the second image data includes generating supplemental color data; modify the second image data in the second color space using at least the converted second color information; and generate a modified image in the first color space using the modified second image data and the generated supplemental color data, wherein the modified image in the first color space comprises modified color information in the first color space based at least in part on the supplemental color data. || 17. A computing system, comprising: at least one processor; and at least one non-transitory memory carrying instructions that, when executed by the at least one processor, cause the computing system to perform operations comprising: receive first image data comprising first color information in a first color space; generate, using the first image data, second image data, wherein the second image data comprises converted second color information in a second color space based on the first color information, wherein multiple color values in the second color space correlate to a same corresponding color value in the first color space, and wherein generating the second image data includes generating supplemental color data; modify the second image data in the second color space using at least the converted second color information; and generate a modified image in the first color space using the modified second image data and the generated supplemental color data, wherein the modified image in the first color space comprises modified color information in the first color space based at least in part on the supplemental color data.
