Abstract: A computing system for adaptive point generation includes a storage to store a densely sampled polyline or surface, or mathematical function, and a processor to compute the area of a contour of the polyline or function with respect to itself, or compute the volume of the surface or function with respect to itself, adaptively resample the polyline, surface, or function, wherein the adaptive resampling is based on and inversely proportional to the computed area or volume, and connect adaptively resampled points as an adaptively sampled polyline or surface.

Abstract: An example non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to generate a first surface based on an edge of a three-dimensional (3D) model. The first surface includes values indicating no displacement at locations of the first surface corresponding to the edge of the 3D model. The instructions, when executed by the processor, cause the processor to merge the first surface with a second surface to produce a third surface. The third surface includes values indicating no displacement at locations of the third surface corresponding to the edge of the 3D model.

Abstract: In an example method, an image to be queried is received. An image representation including symbols is generated from the image via a classifier. A query is received and a target regular expression is generated based on the query. The image representation is queried for a discrete pattern using the target regular expression.

Abstract: In one example in accordance with the present disclosure a three-dimensional illumination chart is described. The chart includes a substrate divided into a number of portions. Each portion includes a raised relief pattern disposed thereon having a relief angle relative to a reference line. Each relief angle of the raised relief patterns of the number of portions is different from other relief angles of other raised relief patterns of other of the number of portions.

Abstract: A system including a memory to store instructions and initial color representations and a processor to execute the instructions in the memory to reference a database having a set of lexical color classifiers, transform each of at least a pair of initial color representations to color values associated with the set of lexical color classifiers, and generate a relative similarity measure related to the at least a pair of initial color representations based on the color values associated with the set of lexical color classifiers.

Abstract: A target and a method to use the target to determine the translucence of media is disclosed. The target has a first region and a second region. The first region comprises a color chart. The second region comprises a test pattern that is covered by the sample media when the sample media is loaded onto the target. The test target has a first area and a second area. An image of the target loaded with the sample media is used to determine the translucence of the sample media. The color of the media over the first and second areas of the test target are matched to the nearest color patches in the image of the color chart. The estimated actual colors of the media over the first and second areas of the test target are determined using the known colors of the nearest color patches. The translucence is determined using the difference between the estimated actual colors of the media over the first and second areas of the test target.

Abstract: A method for colorimetric rendering includes receiving, by a display device, an image that has been preprocessed for adjusting color and disregarding, by the display device, the preprocessing for adjusting color. The display device performs a colorimetric rendering transform at the time of display or print of the image by using an embedded colorimetric reference. A display device for colorimetric rendering of digital images is also provided.
