Effects of video compression artifacts on circular target localization in optical-electronic measurement systems

Several algorithms for accurate circular target localization can be used in optical-electronic measurement systems. In this paper we examine the effects of compression artifacts on the measurement results. We consider image acquisition model of optical-electronic measurement systems and use it to compare accuracy of widely used center of gravity (CoG) algorithm in the presence of compression artifacts. Several compression algorithms are studied in order to determine their influence on the measurement results, including original algorithm for image coding with region of interest (ROI) support.
