Abstract: A device includes a material dispenser and a fluid dispenser. The material dispenser is to dispense a build material layer-by-layer, to at least partially additively form a first 3D object. The fluid dispenser is to dispense at least one fluid agent at selectable exterior voxel locations of the respective layers to at least partially define an external surface of the first 3D object as a first color to represent a first non-color material property of at least a first portion of the first 3D object. The selection of the first color is independent of characteristics of the first non-color material property.

Abstract: An apparatus for backing up a digitally stored image includes a substrate on which the image and digital restoration data corresponding to the digitally stored image are printed on the substrate. The apparatus may be scanned to restore the image printed thereon to its original digital form.

Abstract: Processing of a digital image includes using a machine to convert numerical representations of colors in the digital image to lexical representations of the colors. The lexical representations may be used for image processing such as color reproduction. Examples of lexical-based color reproduction include, without limitation, using the lexical representations to perform color correction of an image display device, identifying potential problems with color shifts, generating statistics about lexical boundary crossings, and developing image processing pipelines.

Abstract: Color transformation sample point identification is described. A subset of points from a superset of points representing a colorimetric relationship is identified. The subset of points defines an initial n-simplex with (n+1) points representing an approximation of the colorimetric relationship, where n represents a number of dimensions. An additional point from the superset of points is selected and added to the subset of points to replace the n-simplex with a set of at least two n-simplices. The additional point is selected such that a volume of an (n+1)-simplex formed by the (n+1) points of the initial n-simplex and the additional point is increased. An error value for the approximation is determined by calculating an error volume between the (n+1)-simplex and the superset of points.
