In this paper,aiming at wavelet denoising using multiple copies corrupted by non-spatially stationary Additive White Gaussian Noise(AWGN),and joint pointwise thresholding and pointwise average together,then compares two different ways of pointwise weighted averages.
对多幅被空间非均匀噪声污染的图像样本提出逐点加权平均与自适应逐点阈值去噪相结合的联合去噪方法,并比较先加权平均(Average)后阈值去噪(Threshold)和先阈值去噪(Threshold)后加权平均(Average)两种不同的方案。
