Abstract: A data-bearing medium has an array of data-bearing elements. The array of data-bearing elements represents an array of bits. A certain number of the bits repeat within the array of bits. Positions of the bits in each row of the array of bits are circularly shifted from positions of the bits in an immediately preceding row.

Abstract: Examples disclosed herein relate to determining image capture position information based on a quasi-periodic pattern. For example, a processor may determine whether a target area is within a captured image based on the detection of a quasi-periodic pattern in a first detection area and in a second detection area of the captured image.

Abstract: An example method of recovering a planar projection in a captured image. The example method includes selecting displaced points in the captured image. The example method also includes recovering an affine transform of a quasi-periodic object for each of the displaced points based on peak locations of Discrete Fourier Transform (DFT) of the captured image. The example method also includes combining each of the affine transforms for the displaced points to recover the planar projection and correct for perspective distortion in the captured image.

Abstract: An example method for forming a data-bearing medium in accordance with aspects of the present disclosure includes setting variables associated with the data-bearing medium, the variables comprising a bit length of a payload, a row-to-row offset and an interleave period, identifying a standard form of the payload, the standard form being a circularly shifted version of the payload, generating a phase code based on the variables, and arranging rows of the data-bearing medium with the standard form of the payload and the phase code based on the interleave period.

Abstract: An example system in accordance with an aspect of the present disclosure includes a halftone engine and a gray value engine. The halftone engine is to apply halftoning to an image recursively across a plurality of levels of image scales and spatial resolutions, to generate a pattern that is at least quasi-periodic across the plurality of levels. The gray value engine is to substitute gray values recursively for at least a portion of the halftoning.

Abstract: A data-bearing image (391) is created from a carrier image (371). The carrier image (371) is scaled to produce a scaled image. A clustered-dot halftone screen is applied to the scaled image to produce a halftone image. A resulting number of cells in the halftone image conforms to a cell count (372) that includes a horizontal cell value and a vertical cell value. Payload data is encoded into the halftone image to produce a data-bearing halftone image, including shifting pixel clusters within cells of the halftone image that include pixel clusters.
