Abstract

A system and method for an efficient semantic similarity search of images with a classification structure are provided. The system and method provide for building a semantic classification-search tree for the plurality of images (202), the classification tree including at least two categories of images, each category of images representing a subset of the plurality of images, receiving a query image (204), classifying the query image to select one of the at least two categories of images (208), and restricting the search for the image of interest using the query image to the selected one of the at least two categories of images (210).

Description

technical field [0001] The present disclosure relates generally to computer graphics processing and display systems, and more particularly to systems and methods for similarity search of images. Background technique [0002] The detection and retrieval of images similar to a query image is very useful in a variety of practical applications. The techniques described in this disclosure address the problem of querying an image database for images that are preferably semantically similar to the query image (ie, images that contain the same objects and background, but possibly with some variation). This problem arises in a variety of applications, such as location-aware services for mobile devices, where a user takes a picture of a landmark and the mobile device can then tell the user the location and description of the landmark. In another application, a user can take a picture of one or more products in a store, and the mobile device can then return a web page of the same prod...
