Abstract: In an example method, a dot pattern of pixels including information to be encoded across an image is mapped to a corresponding subset of the grayscale source pixels corresponding to the image to be printed. A value of a grayscale pixel in the subset of the grayscale source pixels is modified based on based on a predetermined threshold pixel value. The value of the grayscale pixel is decreased in response to detecting that the predetermined threshold pixel value is exceeded. The clipping channel color is used to detect the dot pattern of pixels. The image including the subset of pixels with modified values is printed.

Abstract: In some examples, an imaging device may include a controller including processing circuitry to detect, a first quantity of rows of pixels to be included as a first band of a contone image, process the pixels of each row of the first band in parallel raster order, detect a second quantity of rows of pixels to be included as a second band of the contone image; and process the pixels of each row of the second band in response to the completion of the pixels of the first band, where the rows of the second band are processed in parallel in serpentine order with respect to the first band.

Abstract: According to an example, an apparatus may include a processor and a memory. The memory may have stored thereon machine readable instructions that may cause the processor to access an initial halftone image of a three-dimensional (3D) object, the initial halftone image being generated from a continuous tone image of the 3D object. The instructions may also cause the processor to iteratively modify voxel data for the initial halftone image to identify updated voxel data that more accurately corresponds to the continuous tone image than the initial halftone image and to generate halftone image printing data for the 3D object containing the updated voxel data.

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: A method of forming a data-hiding watermark on a surface may include encoding data within an image using the chrominance data of the of the image, adjusting at least one characteristic of the image to enhance the prominence of the encoded data within the image, and printing the adjusted, encoded image onto the surface.
