A new method for automatic measuring of optical properties of light emitting diodes (LED) was developed. The method is based on projecting LED light on a special screen and on acquiring and analyzing corresponding projection images. The method enables objective evaluation of LED quality, which is of utmost importance for the production of high quality light sources in many applications. The paper was published in a SCI journal with a high impact factor of 1.297, which ranks in the 1st quarter in the field of interdisciplinary applications.

A new protocol for the evaluation of similarity measures for rigid image registration was developed. The proposed protocol is independent of the optimization method and enables objective evaluation of similarity measures. As such, the protocol is a valuable tool for development of new image registration methods. The paper was published in a SCI journal with a high impact factor of 3.275, which ranks in the 4th place out of 227 journals in the field of electrical engineering.
