In brief

Abstract

PAGE 1022 Researchers from the Institute of Image Processing and Pattern Recognition propose a simple algorithm with robust performance. It provides powerful image and video detail enhancement and is particularly useful for practical applications, being easily hardware implemented in field-programmable gate arrays. PAGE 1060 A team from the University of Nantes in France present an accurate model-based method for estimating the position of targets, using a bistatic MIMO radar system. They used factor analysis to estimate components and to precisely locate the targets in terms of Cartesian coordinates. The final enhanced images and videos tend to be more visible and natural looking PAGE 996 Collaboration between the Technical University of Denmark and Chungnam National University in Korea has produced a new circuit layout that enables precise matching of reactive values in small electric and magnetic spherical dipole antennas. The experimental results verified those of the circuit and electromagnetic simulations. GPR and indoor localisation are some typical applications of near field source localisation PAGE 1054 An integrated balancing transformer for a high frequency parallel AC-LED drive circuit is proposed. The team from Gyeongsang National University designed and implemented the transformer, with the experimental results showing the operation and current balancing performance of the proposed scheme. It is expected that the proposed technique will prove useful for high power AC-LED applications. The results of this work can be effectively used in the engineering fields that require small magnetic antennas with wide-band operation PAGE 1045 A team from the Vienna University of Technology suggest an analogue-digital circuit for thermal control of the resonance frequency of optical ring resonators. Compared to a purely analogue heater control, the approach dissipates 7% less power. The approach is appropriate for controlling the individual cells of large optical switch matrices. The engineering application of this work includes high powered LED lighting applications The approach has been successfully verified with a test chip and is very important for the advancement of electronic-photonic integration
