Abstract
Methods, apparatus, and non-transitory computer-readable storage media for editing the colors of objects or regions in digital images. A method for editing images using a color palette is provided. A color palette is described that may be suitable for editing images, which may include specified objects or regions in images. The color palette may display image-specific colors identified using image-dependent techniques described herein. These color palettes may also modify the colors in the image corresponding to the displayed colors in the color palette interface. The method may implement structure-preserving techniques that preserve the structure of the color histogram of the image, thus preserving the natural look of the original image.
