SPEECH ENHANCEMENT BASED ON WAVELET DENOISING
Abstract: - Noise is an unwanted and inevitable interference in any form of communication. It is
non-informative and plays the role of sucking the intelligence of the original signal. Any kind of

盲噪声估计出现在许多图像处理应用的问题，如去噪、COM压缩、分割。在本文中，我们提出了一种新的噪声电平估计方法的基础上的主成分分析的图像块。我们表明，噪声方差可以估计为图像块协方差矩阵的最小特征值。与现有的13种方法相比，所提出的方法显示了良好的速度和精度之间的妥协。这是至少15倍的速度比类似的精度的方法，它是至少两倍的精度比其他方法。我们的方法不假定存在均匀区域的输入图像，因此，可以成功地处理图像只包含纹理。-The problem of blind noise level estimatio

本文提出了一种基于补丁的噪声电平估计算法，补丁产生的单噪声图像。一个可以很容易地估计噪声水平使用主成分分析（PCA）如果图像块的图像只包含弱特将补丁。基于补丁的噪声电平估计的挑战是如何选择弱纹理补丁从嘈杂的图像。去描述在本文中，我们提出了一个选择弱纹理补丁的补丁和基于统计的梯度单噪声图像的新算法。然后，我们估计噪声水平从选定的弱纹理补丁使用PCA。我们实验证明，所提出的噪声电平估计算法优于国家的最先进的算法。-A patch-based noise level estimation algori
