[EN] Digital mammographic image processing often
requires a previous application of filters to reduce the noise
level of the image while preserving important details. This may
improve the quality of digital mamographic ...

[EN] The Undecimated Wavelet Transform is commonly used for signal processing due to its advantages over other wavelet techniques, but it is limited for some applications because of its computational cost. One of the methods ...
Denoising of biomedical signals using wavelet transform is a widely used technique. The use of undecimated wavelet transform (UWT) assures better denoising results but implies a higher complexity than discrete wavelet ...
