On July 3, 2012 two inventors, Erica Cooksey and Els (William) Withers, from Accusoft were awarded a United States Patent for the Methods and Apparatus for Performing Image Binarization.
Image binarization converts an image of up to 256 gray levels to a black and white image. The simplest way to use image binarization is to choose a threshold value, and classify all pixels with values above this threshold as white, and all other pixels as black. The problem then is how to select the correct threshold.
The patent is an algorithm that looks at the content of an image and determines a threshold that will intelligently convert a gray or color image to a black and white image. Specifically, the image binarization works on fine and coarse background features, for example, shaded backgrounds.
"An intelligent algorithm for binarizing an image is an important component in many real-world applications," said Erica Cooksey, Software Engineer at Accusoft. "Accusoft currently uses binarization as a pre-processing step in many of our technologies such as barcode recognition and OCR."
This is Erica's first patent and Els' fifth patent at Accusoft. The complete list of the 19 awarded Accusoft patents can be found on our website.
