Latest Patents

Fadhil 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 cost-effective visible-light scanners. The technology is designed to be invariant to various background colors and artwork typically found in such documents. The invention 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. A series of image processing operations and a pattern recognition algorithm are employed to isolate the graphite response image from a test document by systematically removing the background components. The image processing techniques include grayscale and color segmentation, along with the application of the Hough transform. Components that remain after these operations are identified by calculating their texture features and are subsequently removed using a multivariate Gaussian classifier. Fadhil's innovative approach has the potential to significantly improve the efficiency and accuracy of optical mark recognition systems.
