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.

Claims

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.
