Abstract

The disclosure provides apparatus related to arranging objects (e.g., circles, dots and other shapes) in images and graphics to convey a machine-readable signal. One claim recites an apparatus including: electronic memory for storing image or graphic data; and an electronic processor programmed for: integrating a plurality of objects in stored image or graphic data, the objects being arranged in a pattern that is machine-readable, the plurality of objects being integrated in the image or graphic so that the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic; and providing a visible structure for aiding in machine-reading of the pattern. Of course, other combinations are provided and claimed as well.

Claims

1. An apparatus comprising:

electronic memory configured to store image or graphic data; and

an electronic processor configured to;

integrate a plurality of objects in the image or graphic data, wherein the objects are arranged in a pattern that is machine-readable, and wherein the plurality of objects are integrated in the image or graphic data so that the pattern is hidden in the image or graphic data through cooperation with design elements of the image or graphic data; and

provide a visible structure for aiding in machine-reading of the pattern.

2. The apparatus of claim 1, wherein the plurality of objects comprise dots or circles.

3. The apparatus of claim 1, wherein the cooperation comprises a relationship of color characteristics of the pattern relative to color characteristics of the design elements.

4. An apparatus comprising:

electronic memory configured to store an image or graphic;

an electronic processor configured to;

provide a visible structure for association with the image or graphic, wherein the visible structure aids machine-recognition of a pattern; and

integrate a plurality of objects in the image or graphic, wherein the objects are arranged in the pattern for machine-recognition, and wherein the plurality of objects are integrated in the image or graphic such that the pattern is concealed therein through association with design elements of the image or graphic.

5. The apparatus of claim 4, wherein the objects comprise dots or circles.

6. The apparatus of claim 4, wherein the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic, and wherein the cooperation comprises a relationship of color characteristics of the pattern relative to color characteristics of the design elements.

7. An apparatus comprising:

electronic memory configured to store data representing an image or graphic, and data representing a visible structure, wherein the visible structure is associated with the image or graphic, wherein a plurality of objects are integrated in the image or graphic, wherein the objects are arranged in a machine-readable pattern, wherein the plurality of objects being are integrated in the image or graphic so that the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic, and wherein the visible structure aids in machine-reading of the pattern; and

an electronic processor configured to read the pattern utilizing the data representing the visual structure.

8. The apparatus of claim 7, wherein the objects comprise dots or circles.

9. The apparatus of claim 7, wherein the cooperation comprises a relationship of color characteristics of the pattern relative to color characteristics of the design elements.

10. A method comprising:

storing, in electronic memory, data representing an image or graphic, and data representing a visible structure associated with the image or graphic, wherein the visible structure aids machine-recognition of a pattern, wherein the image or graphic comprises a plurality of objects integrated therein that are arranged in the pattern for machine-recognition, and wherein the plurality of objects are integrated in the image or graphic such that the pattern is concealed therein through association with design elements of the image or graphic; and

recognizing, using an electric processor, the pattern using the data representing the visual structure.

11. The method of claim 10, wherein the plurality of objects comprises dots or circles.

12. The method of claim 10, wherein the pattern is hidden in the image or graphic through cooperation with design elements of the image or graphic, and wherein the cooperation comprises a relationship of color characteristics of the pattern relative to color characteristics of the design elements.
