Optical character recognition on grid and multi-core systems – performance analysis

Requirements of digital libraries for computing power, as well as needs of smaller users for automated document processing and digitization are growing, making grid environments and multi-core systems a preferred platform for optical character recognition applications. This paper examines character recognition performance on the CRO-NGI grid and on two multi-core systems by using from a single core up to all available cores. In addition, different models of load distribution on processing units are used. Comparison of the processing speed and the recognition accuracy is conducted. A developed optical character recognition application for parallel environments is used to obtain the results.
