Using extracted image text
First Claim
Patent Images
1. A computer-implemented method comprising:
- receiving one or more search terms;
identifying, in a collection of images, an image associated with the one or more search terms, the one or more search terms having been extracted from two or more adjacent candidate text regions in the image, the candidate text regions identified as regions of the image containing text; and
providing the image in response to receiving the search terms,wherein the one or more search terms that were extracted from the image were extracted using a text recognition process including;
processing the image to divide the image into one or more regions;
detecting one or more features in each region;
detecting one or more candidate text regions including the two or more adjacent candidate text regions, wherein candidate text regions are regions potentially containing text;
enhancing the candidate text regions to generate an enhanced image; and
performing optical character recognition on the enhanced image.

Abstract
Methods, systems, and apparatus including computer program products for using extracted image text are provided. In one implementation, a computer-implemented method is provided. The method includes receiving an input of one or more image search terms and identifying keywords from the received one or more image search terms. The method also includes searching a collection of keywords including keywords extracted from image text, retrieving an image associated with extracted image text corresponding to one or more of the image search terms, and presenting the image.

9. A system comprising:
-
one or more data processing apparatus; and a computer-readable storage device having stored thereon instructions that, when executed by the one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising; receiving one or more search terms; identifying, in a collection of images, an image associated with the one or more search terms, the one or more search terms having been extracted from two or more adjacent candidate text regions in the image, the candidate text regions identified as regions of the image containing text; and providing the image in response to receiving the search terms, wherein the one or more search terms that were extracted from the image were extracted using a text recognition process including; processing the image to divide the image into one or more regions; detecting one or more features in each region; detecting one or more candidate text regions including the two or more adjacent candidate text regions, wherein candidate text regions are regions potentially containing text; enhancing the candidate text regions to generate an enhanced image; and performing optical character recognition on the enhanced image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
