Abstract The principle of industrial machine monitoring and vehicle camera transmission system are focusing on this paper. Video compression is widely used in many applications like continuous machines which consumes more storage by capturing every motion detection machine, hence video coding highly recommended for without any loss the actual video. By using wavelet transform delivers superior ...

An efficient numerical quadrature for the calculation of the potential energy of wavefunctions expressed in the Daubechies wavelet basis. Abstract. An efficient numerical quadrature is proposed for the approximate calculation of the potential energy in the context of pseudo potential electronic structure calculations with Daubechies wavelet and scaling function basis sets. Our quadrature is als...

Computation in the analog domain is very appealing from a power-consumption perspective. To implement a wavelet transform in an analog circuit, the wavelet function can be approximated by a linear system. An approach based on L2-approximation is presented, that enables largely automated approximation of wavelet functions by impulse responses of linear systems. Various continuous wavelet functio...

This paper presents a new method for electrocardiogram (ECG) denoising based on bivariate shrinkage functions exploiting the interscale dependency of wavelet coefficients. Most nonlinear thresholding methods based on wavelet transform denoising assume that the wavelet coefficients are independent. However, wavelet coefficients of ECG signals have significant dependencies. In this paper, we prop...

A method for designing more regular (more diieren-tiable) scaling functions than the Daubechies wavelets is presented. The approach is to numerically minimize the HH older exponent (a measure of smoothness) subject to constraints on the autocorrelation sequence of the scaling lter. The \maximally smooth" wavelets which result have a HH older exponent which grows faster than that of the Daubechi...

This paper describes the fingerprint verification based on wavelet transform and the local dominant orientation. Daubechies wavelet is use to decompose the fingerprint image. The local dominant orientation is computed using the coherence. The trainee and test fingerprint images are aligned around core point, in this paper the core point is detected as a maximum curvature point. We received 85 p...

In this work, the triple convolution of Daubechies wavelet is used to solve the three dimensional (3D) microscale Dual Phase Lag (DPL) problem. Also, numerical solution of 3D time-dependent initial-boundary value problems of a microscopic heat equation is presented. To generate a 3D wavelet we used the triple convolution of a one dimensional wavelet. Using convolution we get a scaling function ...
