Frequency domain interpolation wavelet transform based algorithm for harmonic analysis of power system

2004 International Conference on Communications, Circuits and Systems (IEEE Cat. No.04EX914), 2004
A power system harmonic detection technique based on a frequency domain interpolation wavelet transform is proposed. Aiming at harmonic detection, a fast Fourier transform (FFT) can only detect integer harmonics; a short time Fourier transform (STFT) can detect non-integer harmonics with low resolution; a wavelet transform can detect non-integer ...

Multiple description discrete cosine transform-based image coding using DC coefficient relocation and AC coefficient interpolation

Journal of Electronic Imaging, 2013
The development of an effective and dependable multiple description coding scheme over a lossy communication system is described. A general framework of an effective multiple description robust communication system with two-channel and four-channel cases is presented with a proposed block-based DC coefficient relo- cation and AC coefficient ...

Wavelet Transform Based Image Interpolation Using PBP Cubic and Hybrid Filter

International Journal of Multimedia and Ubiquitous Engineering, 2016
In this paper, a new wavelet based image interpolation algorithm using pixel-by-pixel (PBP) cubic image interpolation and hybrid filter is proposed for images which include many mid and high frequency elements. There is much important information in frequency bands.

Trace interpolation for irregularly sampled seismic data using curvelet-transform-based projection onto convex sets algorithm in the frequency–wavenumber domain

Journal of Applied Geophysics, 2015
Abstract In recent years, many studies have been performed to reconstruct traces missing from irregularly undersampled seismic data. In this paper, we introduce a new curvelet-transform-based projection onto convex sets (POCS) algorithm that applies the curvelet transform to 2D Fourier-transformed data in the f–k domain instead of data in the t–x ...

Using compute unified device architecture-enabled graphic processing unit to accelerate fast Fourier transform-based regression Kriging interpolation on a MODIS land surface temperature image

Journal of Applied Remote Sensing, 2016
Kriging interpolation provides the best linear unbiased estimation for unobserved locations, but its heavy computation limits the manageable problem size in practice. To address this issue, an efficient interpolation procedure incorporating the fast Fourier transform (FFT) was developed.
