IMAGE TAGGING

摘要

A system is configured to annotate an image with tags. As configured, the system accesses an image and generates a set of vectors for the image. The set of vectors may be generated by mathematically transforming the image, such as by applying a mathematical transform to predetermined regions of the image. The system may then query a database of tagged images by submitting the set of vectors as search criteria to a search engine. The querying of the database may obtain a set of tagged images. Next, the system may rank the obtained set of tagged images according to similarity scores that quantify degrees of similarity between the image and each tagged image obtained. Tags from a top-ranked subset of the tagged images may be extracted by the system, which may then annotate the image with these extracted tags.

1. A method comprising:
accessing an image to be tagged; generating a set of vectors by mathematically transforming the taggable image and regions of the image; querying a database of tagged images by submitting the set of vectors as search criteria to a search engine configured to search the database, the querying of the database obtaining a set of tagged images; ranking the set of tagged images according to similarity scores that quantify degrees of similarity between the image and each tagged image in the set of tagged images; and annotating the image with tags from a subset of the ranked set of tagged images, the annotating being performed by a processor of a machine based on the similarity scores and ranks of tagged images within the subset.
