Latest Patents

Kanneganti holds a patent for "Systems and methods for computationally distinguishing handwritten pencil marks from preprinted marks in a scanned document." This invention presents a method, system, and algorithm that detects graphite responses in optical mark recognition documents using inexpensive visible-light scanners. The technology is designed to be invariant to various background colors and artwork typically found in such documents. It models a superposition of a graphite response image and a background image, which is further modeled as a combination of screening, artwork, lines, and machine text components. The invention employs a sequence of image processing operations and a pattern recognition algorithm to isolate the graphite response image from a test document by systematically removing the components of the background image. The image processing operations include grayscale and color segmentation, along with the application of the Hough transform. Components that are not removed by these operations are identified by calculating their texture features and are subsequently removed using a multivariate Gaussian classifier. Kanneganti's innovative approach has the potential to improve the efficiency and accuracy of document processing systems.
