A method of processing color image watermarking based on the Haar wavelet
Journal of Visual Communication and Image Representation, 2019Abstract Despite the fact that traditional digital watermarking technology is relatively mature, there are still some areas that have not been fully involved in. For example, image watermarking technology and the certification are still in its infancy at early times. The bottleneck problem of digital product safety protection all solved theoretically

Application of Haar’s wavelets in the method of moments to solve electrostatic problems
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2004Presents the mathematical basis and some results, concerning the application of Haar's wavelets, as an expansion function, in the method of moments to solve electrostatic problems. Two applications regarding the evaluation of linear and surface charge densities were carried out: the first one on a finite straight wire, and the second one on a thin ...

Haar wavelets basis method for Nash equilibrium strategies
2008 International Conference on Wavelet Analysis and Pattern Recognition, 2008Haar wavelets method for Nash equilibrium strategies of a time-varying linear-quadratic differential game problem is proposed. Based upon some useful properties of Haar wavelets, a special operation matrix of integration, product and coefficient matrices are applied to the government equation such that the cross-coupled Riccati matrix differential ...

Seamless stitching of images based on a Haar wavelet 2D integration method
2011 17th International Conference on Digital Signal Processing (DSP), 2011A method for seamless stitching of images with photometric inconsistencies in the overlapping region is presented. The method is based on generating a set of stitched gradients from the gradients of the input images and then reconstructing the mosaic image using the Haar wavelet integration technique of [11], [12]. This O(N) reconstruction technique is

Error evaluation of circuit analysis method using Haar wavelet transform
2011 20th European Conference on Circuit Theory and Design (ECCTD), 2011Recently, much attention have been paid to the methods for circuit analysis using wavelet transform. In particular, we have proposed the method which can choose the resolution of the wavelet adaptively. This method can fully bring out the orthogonal and the multiresolution properties of the wavelet, and the efficiency of the calculation can be improved.
