Abstract
A method for enhancing a check code line image of a captured document such as a bank check. The method includes capturing an electronic image of a document; locating a code line region within the electronic image of the document; and performing a localized video gain on the code line region.
Claims10
A method for enhancing a code line in a captured document, comprising:
- capturing an electronic image of a document comprising a check containing a code line region wherein the electronic image is captured as a gray scale image;
- locating the code line region within the electronic image of the document;
- performing a localized video gain on the code line region of the gray scale image to create a blooming effect thereby increasing contrast between optical noise and code line data on the code line region;
- and
- converting the gray scale image to a black-white image.

A method for deploying an application for enhancing a code line in a captured document, comprising:
- providing a computer infrastructure being operable to:
- capture a gray scale image of a document comprising a check containing a code line region;
- locate the code line region within the document;
- perform a localized video gain on the code line region of the gray scale image to create a blooming effect thereby increasing contrast between optical noise and code line data on the code line region;
- and
- convert the gray scale image to a black-white image.
