Abstract: Innovations in encoding or decoding when switching color spaces are presented. For example, some of the innovations relate to signaling of control information for adaptive color space transformation (“ACT”). Other innovations relate to ACT operations. These innovations can improve coding efficiency when switching between color spaces during encoding and decoding.

Abstract: A profile adjustment method includes: accepting first input profile as a first component, accepting at least one of a second input profile and a spot color as a second component combined with the output profile, accepting a first target of adjustment values when color conversion is executed according to the first component and the output profile, accepting a second target of adjustment values when color conversion is executed according to the second component and the output profile, and adjusting the output profile based on the first and second targets. A first output profile may be accepted as the first component combined with the input profile and a second output profile may be accepted as the second component combined with the input profile.

Abstract: The disclosure concerns processing hyperspectral or multispectral images. Image data comprises a sampled image spectrum represented by first values for each pixel location representative of an intensity associated with a wavelength index. A processor determines for each pixel location second values based on a measure of similarity between pixel locations with respect to the first values such that two pixel locations that 5 are similar with respect to the first values are also similar with respect to the second values. The processor then stores for each pixel location the determined one or more second values associated with that pixel location on a data store. This way, the image data is made suitable for applications, such as clustering or displaying, while pixels that are similar in the input image are also similar in the output data. This means that a 10 structure between the pixels in the input image is preserved.

Abstract: In a method of image compression, a processor computes a palette for a block of pixels, the palette having palette values; and the processor computes index values, where some index values map a pixel to a palette value and some index values map a pixel to a value that is between two palette values.

Abstract: The disclosure describes a high dynamic range video coding pipeline that may reduce color artifacts and improve compression efficiency. The disclosed pipeline separates the luminance component from the chrominance components of an input signal (e.g., an RGB source video) and applies a scaling of the chrominance components before encoding, thereby reducing perceivable color artifacts while maintaining luminance quality.

Abstract: A print data generator includes a storage storing processor-executable instructions causing a processor to perform a process to generate print data from original full-color data. The process includes when a hue value of a pixel is within a specific hue range for an emphasis color, setting a density value of a reference color of the pixel based on a value value of the pixel, and setting a density of the emphasis color of the pixel based on a saturation value of the pixel and a difference value between the hue value of the pixel and a hue value of the emphasis color, and when the hue value of the pixel is out of the specific hue range, setting the density value of the reference color based on a luminance value of the pixel derived from RGB data, arid setting the density value of the emphasis color to zero.

Abstract: Systems and methods are provided for generating color names for colors corresponding to images and/or palettes. A color image is obtained, and one or more color palettes corresponding to the color image are identified. The color palette may be generated 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. A color name for each color identified in the color palette and/or the color image can be identified based at least in part on color name popularity information. Color name popularity information may be identified from color name-related voting results provided by a social network site. Aspects of the disclosure are further directed to processing the identified color name(s), such as updating color name metadata associated with the original color image and/or the color palette.

Abstract: An example embodiment may involve obtaining (i) an a×b attribute macro-cell, and (ii) a×b pixel macro-cells for each of a luminance plane, a first color plane, and a second color plane of an input image. The a×b pixel macro-cells may each contain 4 non-overlapping m×n pixel cells. The example embodiment may also involve determining 4 attribute-plane output values that represent the 4 non-overlapping m×n attribute cells, 1 to 4 luminance-plane output values that represent the a×b pixel macro-cell of the luminance plane, a first color-plane output value to represent the a×b pixel macro-cell of the first color plane, and a second color-plane output value to represent the a×b pixel macro-cell of the second color plane. The example embodiment may further involve writing an interleaved representation of the output values to a computer-readable output medium.

Abstract: Systems and methods for generating an image-based color palette based on a color image. A color palette can be a collection of representative colors each associated with a weight or other metadata. A color palette may be generated 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.
