In this paper, we propose a novel SVD-based RGB color image watermarking, in which the watermark is assumed to be an RGB color image whose detection and extraction are performed in a blind manner. The performance of the proposed watermarking method is investigated by measuring its imperceptible and robust capabilities. For the imperceptible capability, a(More)
Fully digital AC drives with pulse width modulator inverters are becoming an industrial standard. For PWM inverters the most commonly used is the conventional sine PWM (SPWM). An attempt to improve this carrier based strategy is presented by means of the introduction of discontinuous techniques; such as the dead band PWM (DBPWM) and the modified SPWM(More)
In this paper, we propose a new Multi-Objective Optimization (MOO) approach using the second version of non-dominated sorting genetic algorithm (NSGA-II) for Blind RGB color image watermarking. The design of an optimal watermarking for a given application always involves a tradeoff between imperceptibility requirement and robustness requirement. Therefore,(More)
The current controlled voltage source inverter fed PMSM has received wide spread interest in high performance vector control and motion control applications. Hysteresis controllers are intrinsically robust to system parameters, exhibit very high dynamics and are suitable for simple implementation. The main drawback of the hysteresis controller is a limited(More)
