Image Processing and Pattern Recognition
We partnered with Learning Egg, LLC to co-develop Lightning Grader, a web-based application for generating assessments that adhere to state standards and optically grades assessments using registration and marker recognition. Our rapid marker recognition algorithm is capable of grading exams at a rate of 30 pages a minute using standard bulk scanners typically available in large school systems. The system is scheduled to go live December 2011, and is currently under beta-testing in several charter schools within the Youngstown, OH area.
Other projects include photo-correcting algorithms for red eye removal, color temperature correction, and thumbnail generation.

Flash-based Computer Adaptive Testing
Questions are adjusted to a user’s response. The questions become easier or more difficult depending on how the user answers questions. By doing this the test does not have to have hundreds of questions to get the accuracy of a test consisting of hundreds of questions.
The testing has the potential to be beneficial in many different areas. One big area is applying the test for rapid assessment of prospective employees. Another area of application would be to use the test in specialized forums to determine the user’s expertise in that area.
