Image pattern recognition using mobile devices

Image pattern recognition has been so far carried out almost exclusively using sophisticated and expensive software solutions and devices. Mobile devices have evolved to the extent that they can be used for such purpose, but the algorithms and systems that provide such functionalities in real time are rare. This paper describes the development of an algorithm within PEAS system, which enables the identification of answers in scorecard paper sheet using mobile devices. Thereby we will show the theoretical basis of the image pattern recognition, implementation of the algorithm using the OpenCV library and JavaCV, and the practical experience in such an approach.
