Abstract
In an example, a method includes, by one or more processors, acquiring a dot pattern having a distribution of dots. A greyscale image comprising a plurality of pixels each associated with a greyscale value may be derived from the dot pattern. Deriving the greyscale image may comprise, for each pixel, determining the closest dot to the pixel and associating a distance of the closest dot from the pixel with the pixel, and assigning a greyscale value to each pixel, wherein the greyscale value is based on the distance associated with that pixel.
Claims15
A method comprising, by one or more processors:
- acquiring a dot pattern having a distribution of dots;
- deriving, from the dot pattern, a greyscale image comprising a plurality of pixels each associated with a greyscale value, wherein deriving the greyscale image comprises:
- for each pixel, determining the closest dot to the pixel and associating a distance of the closest dot from the pixel with the pixel;
- and
- assigning a greyscale value to each pixel, wherein the greyscale value is based on the distance associated with that pixel.
Processing circuitry comprising:
- a pattern module, to determine a dot pattern;
- and
- a greyscale module to determine a greyscale image of the dot pattern, the greyscale image comprising a plurality of pixels each associated with a greyscale value, wherein the greyscale module is to determine, for each pixel, a distance between that pixel and the closest dot and to assign a greyscale value to the pixel based on the distance.
Non-transitory machine readable medium storing instructions which, when executed, cause a processor to:
- derive a greyscale image from an image comprising distributed points by assigning a greyscale level to each pixel which is proportional to a distance from the closest point to that pixel, wherein a pixel which has a closest point having a first distance is assigned a lower greyscale level than a pixel which has a closest point having a second distance, wherein the second distance is greater than the first distance.
