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, 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, classifying the query image to select one of the at least two categories of images, 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.
Claims26
A method for searching a plurality of images for an image of interest, the method comprising the steps of:
- building a classification structure for the plurality of images, the classification structure including at least two categories of images, each category of images representing a subset of the plurality of images;
- receiving a query image;
- classifying the query image to select one of the at least two categories of images;
- and
- restricting the search for the image of interest image to the selected one of the at least two categories of images.
A system for searching a plurality of images for an image of interest comprising:
- a database including a plurality of images structured into at least two semantic categories of images, each semantic category of images representing a subset of the plurality of images;
- means for acquiring at least one query image;
- an image classifier module for classifying the query image to select one of the at least two semantic categories of images;
- and
- an image searcher module for searching for the image of interest using the query image, wherein the search is restricted to the selected one of the at least two semantic categories of images.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for searching a plurality of images for an image of interest, the method comprising the steps of:
