TEXT-BASED SEARCHING OF IMAGE DATA
First Claim
1. A method for text-based searching of image data comprising:
- with a computer processor, computing a measure of string similarity between a query and an annotation associated with each of a plurality of entries in a first database;
based on the computed string similarity measures, selecting a set of the entries from the associated first database, a visual signature being associated with each entry;
retrieving at least one entry from a second database, based on a measure of visual similarity between a visual signature of each of a plurality of entries in the second database and the visual signatures of the entries in the selected set; and
generating information corresponding to the least one of the retrieved entries.

Abstract
A method and system are disclosed for conducting text-based searches of images using a visual signature associated with each image. A measure of string similarity between a query and an annotation associated with each entry in a first database is computed, and based upon the computed string similarity measures, a set of entries from the first database is selected. Each entry of the first database also includes an associated visual signature. At least one entry is then retrieved from a second database based upon a measure of visual similarity between a visual signature of each of the entries in the second database and the visual signatures of the entries in the selected set. Information corresponding to the retrieved entries from the second database is then generated.

17. A text-based image searching system, comprising:
-
a processor with access to associated memory, the associated memory storing; a first associated database comprising a plurality of annotated entries, each entry having a visual signature and annotation associated therewith, and a second associated database comprising a plurality of entries, each entry having a visual signature associated therewith; memory in communication with the processor, which stores instructions which are executed by the processor for; receiving a query which comprises a character string, computing a string similarity measure between the query character string and an annotation associated with each of a plurality of entries in the first database, based on the computed string similarity measures, selecting a set of the entries from the associated first database, a visual signature being associated with each entry, retrieving at least one entry from a second database, based on a computed visual similarity measure which is based on visual signatures of each of a plurality of entries in the second database and the visual signatures of the entries in the selected set from the associated first database, and outputting information corresponding to the least one of the retrieved entries. - View Dependent Claims (18, 19)

20. A method for text-based searching of image data comprising:
-
receiving a query into memory, the query comprising a character string, each of the characters in the string being selected form a finite set of characters; with a computer processor, calculating a string similarity measure between the character string of the query and an annotation associated with each of a plurality of visual signatures of captured images stored in a first database, the annotation comprising a character string, each of the characters in the string being selected from the finite set of characters; selecting a first set of visual signatures from the plurality of visual signatures in the first database based on the computed string similarity measures; retrieving a set of images from a second database based on a computed measure of similarity between the visual signatures in the first set of visual signatures and visual signatures of images in the second database. - View Dependent Claims (21, 22, 23, 24)
