A novel approach was proposed to denoise the Doppler ultrasound signal. Using this method, wavelet coefficients of signal at multiple scales were first obtained using discrete frame analysis. Then, a soft thresholding-based denoising algorithm employed deal with these get denoised In simulation experiments, SNR improvements and maximum frequency estimation precision studied for From clinical studies, it concluded that performance (DWF) is higher than standard (critically sampled) transform...
Image fusion method based on separable discrete wavelet transform has block effect and the spatial resolution is lower in result images. The design of filter bank relies form dilation matrices image three‐channel non‐separable wavelet. To resolve these problems, a new construction banks symmetric with arbitrary presented. A multispectral this kind proposed. An example those properties constructed applied to panchromatic image. experiment results show that good visual effect. performance...
Cloud attack provenance is a well-established industrial practice for assuring transparency and accountability service provider to tenants. However, the multi-tenancy self-service nature coupled with sheer size of cloud implies many unique challenges forensics. Although Virtual Machine Introspection (VMI) powerful tool due privilege isolation, stealthiness state-of-the-art attacks lack precise information make existing solutions difficult fulfill real-time forensics when tracking enormous...
Querying live media streams captured by various sensors is becoming a challenging problem, due to the data heterogeneity and lack of unifying model capable accessing multimedia providing reasonable abstractions for query purpose. In this paper we propose system that enables directly capturing from automatically generating more meaningful feature can be queried stream processor. The provides an effective combination between extendible digital processing techniques general management research.
With the development of large field-of-view and high precision star sensor technology, ship attitude can be measured using sensor, then measurement accuracy measuring equipments in Spacecraft Tracking, Telemetry Command (TT&C) improved greatly. According to non-Gaussian nonlinear characteristics data, a filtering algorithm based on wavelet domain Hidden Markov Model(HMM) model is proposed this paper. The establishes models between coefficients data HMM model, which parameters are estimated...
In order to solve the problems that Daubechies series of wavelets have not symmetry and separable discrete wavelet transforms only emphasize horizontal vertical directions decomposed images, a novel fusion method multi-focus images based on three channel nonseparable symmetrical is proposed. A construction filter banks relating this kind presented. The multi-resolution decompositions image are performed in nonsubsampled mode using constructed. rule value smaller selected for low frequency...
A construction method of three channels non-separable wavelet filter bank is presented and a multispectral image fusion based on this kind proposed. The approximation images the detail multi-resolution pyramid decompositions are fused. experiment results show that has good visual effect. performance outperforms IHS method, DWT IHS-DWT in preserving spectral quality high spatial resolution information.
In this paper, our purposes are image compression code by wavelet transformation, and develop a novel encoding algorithm structure of DPCM/WT on the basis DPCM/DCT. We have proposed new based object driving data flow driving, in property is superior to DPCM/DCT ratio, fidelity real time processing.
