Recognizing text in images
First Claim
1. A computer-implemented method for recognizing text in an image, comprising:
- receiving a plurality of images;
processing the images to detect a corresponding set of regions of the images, each image having a region corresponding to each other image region, as potentially containing text;
combining the regions to generate an enhanced region image; and
performing optical character recognition on the enhanced region image.

Abstract
Methods, systems, and apparatus including computer program products for recognizing text in images are provided. In one implementation, a computer-implemented method for recognizing text in an image is provided. The method includes receiving a plurality of images. The method also includes processing the images to detect a corresponding set of regions of the images, each image having a region corresponding to each other image region, as potentially containing text. The method further includes combining the regions to generate an enhanced region image and performing optical character recognition on the enhanced region image.

18. A computer-implemented method for recognizing text in an image, comprising:
-
receiving an image; processing the image to divide the image into one or more regions; detecting one or more features in each region; determining for each region whether it is a candidate text region potentially containing text using the detected features; enhancing the candidate text regions to generate an enhanced image; and performing optical character recognition on the enhanced image. - View Dependent Claims (19, 20, 21, 22, 23)
