NVF thresholding of DWT coefficients

Subject: NVF thresholding of DWT coefficients

Message: 1 of 3

I want to find out the significant DWT(discrete wavelet transform) coefficients using a threshold which is based on Noise Visibility Function(NVF). I've searched the web a lot but didn't find any resources.
Is it possible? If so ,please give some feedback.

Thanks in Advance.

You would have to write the MATLAB code to calculate the thresholds for that denoising method yourself, but then you can easily apply those thresholds to your wavelet coefficients using

wdencmp()
