Using extracted image text
First Claim
Patent Images
1. A computer-implemented method comprising:
- receiving a plurality of different images of a first scene, wherein each image has a different exposure level;
compositing two or more images into a composite image using the plurality images;
detecting one or more features in each of one or more regions of the composite image;
determining for each region of the composite 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.

11. A system comprising:
-
one or more data processing apparatus; and a data store storing 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 a plurality of different images of a first scene, wherein each image has a different exposure level; compositing two or more images into a composite image using the plurality images; detecting one or more features in each of one or more regions of the composite image; determining for each region of the composite 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
