On Choosing a Non-integer Resolution Level When Using Wavelet Methods
نویسندگان
چکیده
In curve estimation using wavelet methods it is common to select the resolution level to be an integer, so as to exploit the computational advantages of the pyramid or cascade algorithm. This choice, however, can produce a noticeable amount of either oversmoothing or undersmoothing. Its analogue for estimation by kernel methods is to restrict the bandwidth to be an integer power of 1 2 , which would seldom be acceptable. In this note we quantify the advantages of non-integer resolution levels.

Design of Dyadic-integer-coefficients Based Bi-orthogonal Wavelet Filters for Image Super-resolution Using Sub-pixel Image Registration
This paper presents image super-resolution scheme based on subpixel image registration by the design of a specific class of dyadicinteger-coefficient based wavelet filters derived from the construction of a half-band polynomial. First, the integer-coefficient based halfband polynomial is designed by the splitting approach. Next, this designed half-band polynomial is factorized and assigned spec...
متن کاملImage Steganalysis Based on Co-Occurrences of Integer Wavelet Coefficients
We present a steganalysis scheme for LSB matching steganography based on feature vectors extracted from integer wavelet transform (IWT). In integer wavelet decomposition of an image, the coefficients will be integer, so we can calculate co-occurrence matrix of them without rounding the coefficients. Before calculation of co-occurrence matrices, we clip some of the most significant bitplanes of ...
متن کاملPermeability upscaling in fractured reservoirs using different optimized mother wavelets at each level
We use a multi-resolution analysis based on a wavelet transform to upscale a 3D fractured reservoir. This paper describes a 3D, single-phase, and black-oil geological model (GM) that is used to simulate naturally-fractured reservoirs. The absolute permeability and porosity of GM is upscaled by all the possible combinations of Haar, Bior1.3, and Db4 wavelets in three levels of coarsening. The ap...
متن کاملCan Wavelet Denoising Improve Motor Unit Potential Template Estimation?
Background: Electromyographic (EMG) signals obtained from a contracted muscle contain valuable information on its activity and health status. Much of this information lies in motor unit potentials (MUPs) of its motor units (MUs), collected during the muscle contraction. Hence, accurate estimation of a MUP template for each MU is crucial. Objective: To investigate the possibility of improv...
متن کاملSome New Methods for Prediction of Time Series by Wavelets
Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...
