In order to reduce the musical residual noise and the background noise, a speech enhancement method based on masking properties of the human auditory system is described. this method uses bark wavelet packet transform to simulate the frequency feature of human auditory model to get the threshold
本文以最大限度減少殘留噪聲和背景噪聲為目的，採用bark子波分析的方法模擬人耳基底膜的頻率分析特性來進行語音增強，重點進行模擬人耳聽覺掩蔽效應來確定除噪閾值的研究。 -
We propose an algorithm, which integrate the shift invariance of redundant discrete wavelet transformation ( rdwt ) and the flexibility of multi - resolution motion estimation, to overcome the shift variance of dwt and get the precise motion vector. under the different code parameter, we take the proposed algorithm compared to several present algorithms, and experiment results have shown that proposed algorithm could leave less energy in the residual frames, get more precise motion vector and better reconstructed frames
文章最後在不同的編碼參數下，將所提演算法與兩種傳統小波域運動估計演算法作比較，根據實驗所得數據分析，發現所提演算法在性能上要優于另外幾種演算法，具體體現在運動估計后所得殘差幀能量更小，重構幀客觀與主觀質量更高。 -
Doing the further research on the division frequency stack on the foundation of study of predecessor, at first the residual moveout correction is done to the seismic record, make the phase axle regularity, doing foundation for the same phase stack ; then carried on division scale processing by wavelet transform ; spectrum whitening is done to each scale, the high and low frequency band need to do prolongs, the middle frequency bands only increase the value of the frequency spectrum ; several kinds of methods that estimate the value of signal - noise ratio has been studied further, and summarize their advantage and disadvantage as well as the scope of application ; the seismic record after spectrum whitening is stacked by weighting with the value of the signal - noise ratio ; then estimate the value of signal - noise ratio which is each scale section after stacking, the scale that the signal - noise ratio is big is assigned big weighting, otherwise, the scale that signal - noise ratio value is small is assigned small weight ing, and carried on weighted reconstruct to each scale section
本文在前人研究的基礎上，在分頻疊加方面做了進一步的研究。首先對地震記錄進行剩餘時差校正，校齊同相軸，為同相疊加做好基礎工作；然後對地震記錄用小波變換的方法進行分尺度處理；對各個尺度分別做譜白化，對于高、低頻段需要做頻帶延拓，中間頻段僅提升頻譜值；對于幾種信噪比定量估計的方法進行了深入的研究，並且總結了它們的優缺點以及適用范圍；對譜白化后的地震記錄用信噪比估計值作為加權系數進行加權疊加；對于各尺度的疊加剖面也進行信噪比估計，對于信噪比大的尺度給予大的加權系數，反之，信噪比值小的尺度給予小的加權系數，對各尺度疊加剖面進行加權重構。 -
In this paper semiparametric regression is presented to solve the problem, moreover the algorithm is given. it is an iterative process between linear estimation and nonlinear estimation. the linear estimation is ls estimation and the nonlinear estimation is a wavelet denoising process of residual
本文提出的半參數回歸方法較好的解決了上述問題，並給出了相應的演算法：這是一種線性估計和非線性估計相互迭代的方法，線性估計是最小二乘法，而非線性估計是基於小波對殘差去噪的方法。 -
