Performing image similarity operations using semantic classification

摘要

Image similarity operations are performed in which a seed image is analyzed, and a set of semantic classifications are determined from analyzing the seed image. The set of semantic classifications can include multiple positive semantic classifications. A distance measure is determined that is specific to the set of semantic classifications. The seed image is compared to a collection of images using the distance measure. A set of similar images is determined from comparing the seed image to the collection of images.

1. A computer-implemented method, comprising:
obtaining a query image of an object; identifying multiple classes of objects for the object; for each of the identified multiple classes of objects, (i) identifying a distance function associated with the class of objects and (ii) identifying reference images associated with the class of objects; for each of the identified reference images, determining a similarity score between the reference image and the query image based on the identified distance functions; selecting one or more of the reference images based on the determined similarity scores; and providing the selected one or more of the reference images.
