I use computer vision to automate visual tasks in the entire life cycle of interactive software including design, prototyping, development, testing, deployment, maintenance and support. My most significant research contribution so far is Sikuli Script, a GUI automation tool using screenshots. Since its release in 2010, it has been downloaded more than 200,000 times and used by a large community of users for a variety of purposes such as testing, IT automation, scraping, data transfer, and gaming.
