Abstract
A method of object identification includes: capturing an image of an object having a material presenting surface artifacts; detecting a boundary within the captured image; selecting a portion of the image depicting the surface material within the boundary; based on the selected portion of the image, determining attributes of the surface artifacts; generating, based on the determined attributes of the surface artifacts, a physical identifier corresponding to the object; and storing the generated physical identifier.
Claims21
A method of object identification, the method comprising:
- capturing an image of an object having a material displaying surface artifacts;
- detecting a boundary within the captured image;
- selecting a portion of the image depicting the material within the boundary;
- determining, based on the selected portion of the image, at least one attribute of the surface artifacts;
- generating, based on the determined at least one attribute of the surface artifacts, a physical identifier corresponding to the object;
- and
- storing the generated physical identifier.
A computing device, comprising:
- a memory;
- a sensor;
- and
- a processor configured to:
- control the sensor to capture an image of an object having a surface material presenting surface artifacts;
- detect a boundary within the captured image;
- select a portion of the image depicting the surface material within the boundary;
- determine, based on the selected portion of the image, at least one attribute of the surface artifacts;
- generate, based on the determined at least one attribute of the surface artifacts, a physical identifier corresponding to the object;
- and
- store the generated physical identifier.
A label, comprising:
- a fibrous face stock member having surface artifacts;
- a uniform coating extending over a first portion of an outer surface of the face stock member, the coating configured for pigmentation responsive to a media processing operation;
- and
- a window in the coating, the window extending over a second portion of the outer surface distinct from the first portion to reveal the surface artifacts.
A supply of labels, comprising:
- a fibrous liner layer having surface artifacts;
- a printable substrate layer comprising a plurality of labels separated by respective gaps;
- an adhesive between the fibrous liner layer and the printable substrate layer;
- and
- a data carrier encoding a physical identifier derived from at least one optical measurement of the surface artifacts of the liner layer within at least one of the gaps.
