An Improved Wavelet Denoising via Empirical Wiener Filtering
Yuqing Li · Modern Electronic Technique · 2005
The traditional empirical Wiener filtering demands the piloting wavelet matching with the denoising wavelet, but how to match has not a qualified result and only an empirical rule is gained by experimental result. This paper uses the joint image denoising result via multiple wavelet bases as piloting image, and estimates the variance of the real signal.So the wavelet matching is avoided, also an apparently result is achieved.
