Abstract
Various embodiments of the invention describe a method, system and computer-readable storage medium containing instructions for improving the recognition of text present in an image. The image is processed by applying different operators to the image to obtain multiple processed versions of the image. Thereafter, characters and location information of the characters from each of the multiple processed versions of the image are obtained. The location information includes the pixel coordinates of the characters in the text. The text present in the image is edited, based on the relative location of the characters, to improve the recognition of the text in the image.
