鈥 -is the closed-form solution to the following optimization problem: (4) This property leads to the relaxation algorithm of Sec- tion II-A and to the definition of basis pursuit. When is no longer orthonormal but overcomplete, the least squares estimate no longer has independent components...
Based on the definition of zero bias and zero drift in the fiber optic gyro (FOG),several de-noising algorithms on wavelet analysis are analyzed and the signal of FOG is processed. According to the results using several different basic wavelets, a method fitting engineering practice is proposed...

We comment informally on the contest between these transforms in signal processing, especially for video and image compression (including high-definition television). So far the Fourier Transform --- or its 8 by 8 windowed version, the Discrete Cosine Transform --- is often chosen. But wavelets...
The paper introduces the definition of wavelet transform and its properties.Especially the philosophy for zero-crossing wavelet and how it can be used in seismic prospecting are presented.According to the calculation of model,we can recognize the layer depth up to λ/6 from synthetic wave reflected...

It offers advantages over Fourier transformation by providing flexibility in handling signals with sharp spikes and discontinuities, and by capturing information on when frequencies occur. AI generated definition based on: An Industrial IoT Approach for Pharmaceutical Industry Growth, 2020...
Although wavelet has been developed over about ten years in the mathematics and physics, its engineering applications is a first stage. The objective of this report outlines the definition of the wavelet transform and is to discuss the properties of the wavelet transform as new tool for the ...
We propose a new subspace decomposition scheme called anisotropic wavelet packets which broadens the existing definition of 2-D wavelet packets. By allowin... X Dan,MN Do - Proceedings of SPIE - The International Society for Optical Engineering 被引量: 59发表: 2003年 S2LET: A code to perform...
