Abstract
The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.
Claims20
A system, comprising:
- an illumination source configured to direct incident light to a dendritic structure in a tag attached to an article or to a container comprising the article;
- a detector configured to obtain an image by measuring incident light reflected from the dendritic structure;
- and
- at least one electronic processor configured to:
- segment the image into a plurality of regions and assign a binary value to each region based on the portion of the dendritic structure in each region;
- construct a binary spatial representation of the dendritic structure based on the plurality of regions;
- and
- compare the binary spatial representation to reference information for a plurality of dendritic structures to determine information about the article.
