Matrix barcode having a plurality of colors and a least prevalent color
An article of manufacture may include a matrix barcode on a physical medium and associated with an environment. The matrix barcode may include a plurality of colors, where at least one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment.
1. An article of manufacture, comprising:
a matrix barcode on a physical medium and associated with an environment, the matrix barcode comprising a plurality of colors, wherein at least one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment wherein the matrix barcode is further based on a first plurality of colors derived from a plurality of least prevalent colors in the environment.
2. The article of manufacture of claim 1 , wherein the physical medium is a physical material and the matrix barcode is embedded thereon.
3. The article of manufacture of claim 1 , wherein the physical medium is a computer display that displays the matrix barcode.
4. The article of manufacture of claim 1 , wherein at least a second one of the plurality of colors of the matrix barcode is a color absent in the environment.
5. The article of manufacture of claim 1 , wherein the matrix barcode includes at least four distinct colors, wherein each of the at least four distinct colors are different than a most prevalent color of the plurality of prevalent colors in the environment.
6. The article of manufacture of claim 5 , wherein the plurality of prevalent colors includes a plurality of most prevalent colors in the environment, wherein each of the at least four distinct colors are different than the plurality of most prevalent colors.
7. The article of manufacture of claim 5 , wherein the matrix barcode is derived from a red-green-blue (RGB) colorspace and a derivative colorspace of the RGB colorspace, wherein the derivative colorspace includes a filtered luminance channel.
8. The article of manufacture of claim 1 , wherein the matrix barcode is based at least in part on a conversion from a first colorspace to a second colorspace.
9. The article of manufacture of claim 1 , wherein each of the plurality of colors comprise non-black or non-white colors.
10. The article of manufacture of claim 1 , wherein the matrix barcode is embedded with computer data.
11. The article of manufacture of claim 10 , wherein the computer data is represented by a plurality of pixels associated with the plurality of colors.
12. The article of manufacture of claim 11 , wherein the plurality of colors are associated with at least three color channels, wherein the plurality of pixels are associated with the at least three color channels.
13. The article of manufacture of claim 1 , wherein the matrix barcode includes four or more bits of information.
14. The article of manufacture of claim 1 , wherein the matrix barcode includes an infrared layer and an ultraviolet layer.
15. The article of manufacture of claim 1 , wherein the matrix barcode encodes a verification bit to indicate a presence of an infrared layer or an ultraviolet layer of the matrix barcode.
16. The article of manufacture of claim 1 , wherein the matrix barcode includes an infrared layer.
17. The article of manufacture of claim 1 , wherein the matrix barcode includes an ultraviolet layer.
18. An article of manufacture, comprising:
a matrix barcode on a physical medium and associated with an environment, the matrix barcode comprising a plurality of colors, wherein at least a first one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment, wherein at least a second one of the plurality of colors is a color absent in the environment.
19. The article of manufacture of claim 18 , wherein the matrix barcode is based at least in part on a conversion from a first colorspace to a second colorspace.
20. An article of manufacture, comprising:
a matrix barcode on a physical medium and associated with an environment, the matrix barcode comprising a plurality of colors, wherein at least one of the plurality of colors is a least prevalent color, of a plurality of prevalent colors in the environment, wherein the matrix barcode includes at least four distinct colors, wherein each of the at least four distinct colors are different than a most prevalent color of the plurality of prevalent colors in the environment.
