Abstract: Wavelet thresholding (or shrinkage) attempts to remove the noises existing in the signals while preserving inherent pattern characteristics in the reconstruction of true signals. For data-denoising purpose, we present a new wavelet thresholding procedure which… read more here.

DOI: 10.1109/tmech.2019.2898509
Abstract: This paper focuses on the design of a 6 degrees of freedom visual servoing control law. Instead of using geometric visual features in standard vision-based approaches, the proposed controller makes use of wavelet coefficients as… read more here.

DOI: 10.3390/sym15040803
Abstract: This paper addresses how to use high-order diffusion to restore the wavelet coefficients in the wavelet domain. To avoid image distortion, wavelets with symmetry are used for image decomposition to obtain the wavelet coefficients of… read more here.
