| This method does not solve data fitting problem in an optimal way, as using regularizer for denoising images is not a specialized one. |
| To highlight the denoising capacity of the wavelet multiresolution analysis, one calculated the kurtosis and the peak value of the original and the reconstructed signals. |
| If signal denoising is a target application of the filter bank then the decimators can be removed and filters P and U upsampled, resulting in an undecimated transform. |
| The image denoising is represented using three techniques namely spatial domain, transform domain, and dictionary learning based on wavelet to represent the image. |
