A scheme for energy compensation is proposed to remedy the deficiency of the DWT-DCT based scheme while applying the quantization index modulation (QIM) to perform blind audio watermarking. Our experimental results show that both the compensated and uncompensated DWT-DCT schemes can achieve satisfactory robustness and imperceptivity at a payload capacity as high as 516.80 bps. However, because of...
Non-local means provides a very powerful framework to denoise digital images. Nevertheless, there are several influential parameters on this methodology that are data-dependent and difficult to tune. This paper presents an adaptive image denoising algorithm that uses the non-local means in conjunction with the turbulent particle swarm optimization (i.e. TPSO) which based on a no-reference metric Q...
This paper presents a novel vehicle full-state estimation and prediction system that employs a ldquofull-state vehicle modelrdquo together with lateral acceleration, longitudinal velocity, and suspension displacement sensors to obtain the current and future vehicle state information. The full-state vehicle model is a vehicle model with 6 degrees of freedom (DOFs) and is described by 20-state nonlinear...
