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.
Claims19
A computer-implemented method comprising:
- receiving a plurality of different images of a first scene, wherein each image has a different exposure level;
- generating a high dynamic range image using the plurality images;
- detecting one or more features in each of one or more regions of the high dynamic range image;
- determining for each region of the high dynamic range image whether the region is a candidate text region potentially containing text based on the detected one or more features;
- and
- generating text by performing optical character recognition on a plurality of the regions determined to contain text.
A system, comprising:
- one or more processing devices;
- and
- a memory storage apparatus in data communication with the one or more processing devices and storing instructions that cause the one or more processing devices to perform operations comprising:
- receiving a plurality of different images of a first scene, wherein each image has a different exposure level;
- generating a high dynamic range image using the plurality images;
- detecting one or more features in each of one or more regions of the high dynamic range image;
- determining for each region of the high dynamic range image whether the region is a candidate text region potentially containing text based on the detected one or more features;
- and
- generating text by performing optical character recognition on a plurality of the regions determined to contain text.
