A neural and interpolation method for wavelet transform based image compression
TENCON 2007 - 2007 IEEE Region 10 Conference, 2007The characteristics of providing spatial and frequency information in the transform domain by wavelet transform, plays a crucial role in forming a significance map of coefficients that needs to be coded in the case of image compression. This paper presents a wavelet based image compression technique where transmission of spatial locations of wavelet ...

Undecimated Wavelet Transform-Based Image Interpolation
2010In this paper, a new wavelet-based image interpolation algorithm is developed for magnifying the image details so that the visibility of tiny features in a digital image is improved. The algorithm takes the LR image as the low-pass filtered subband of an unknown wavelet transformed high resolution image.

Wavelet transform based new interpolation technique for satellite image resolution enhancement
2014 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology, 2014In this research paper, we propose a new interpolation technique based on the Stationary Wavelet Transform (SWT) and iterative back projection (IBP) for satellite images. Firstly the low resolution image is interpolated by using bicubic interpolation and then decomposed into different subband images by SWT.

Windowed interpolated discrete Fourier transform (DFT) has been well-studied to deal with the spectral leakage and picket fence effects in frequency estimation. When the number of acquired sine-wave cycles is small, the long-range spectral leakage of the negative frequency is the main cause of low accuracy.

A 1.2V, 17dBm digital polar CMOS PA with transformer-based power interpolating
ESSCIRC 2008 - 34th European Solid-State Circuits Conference, 2008Targeting for WLAN applications, this paper presents a digital polar power amplifier in a 65 nm digital CMOS process, with 17 dBm maximum RMS output power at 1.2 V supply voltage. To reduce the out-of-band alias caused in the direct digital-to-RF power conversion, a transformer-based power interpolating technique is implemented.

On the orthogonality of anti‐leakage Fourier transform based seismic trace interpolation
SEG Technical Program Expanded Abstracts 2004, 2004Summary Seismic data regularization, which aims to estimate the seismic traces on a spatially regular grid using the a cquired irregular sampled data, is an interpolation/extrapolation problem. Sampling theory offers the basic conditions for all the seismic data regularization implementations.

Abstract The calculation of three-dimensional dose rate fields plays a key role in radiation dose rate estimation and the service for the nuclear emergency. The recent fast calculation method based on the Fast Fourier Transform (FFT) method can greatly speed up the calculation without losing accuracy, which is promising for operational ...

A Local Transformation-based Constraint-guidedGMP Compatible with an Interpolation Scheme
2017 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2017 The T-CGMP inference scheme combines the GMP principles with additional constraints to guide inference in the case where the observation does not match the rule premise. This paper studies its exploitation in the case where several rules are available, in particular considering the case of two rules: it proposes a local variant of T-CGMP and examines ...

Adaptive directional wavelet transform based on edge directed interpolation for image coding
2012 Third Asian Himalayas International Conference on Internet, 2012We propose a new image compression method based on directional wavelet transform. The proposed method exploits the local characteristics of image by combining the wavelet filters adaptive to edge orientation with quincunx sub sampling to form a 2-D non separable transform through lifting.
