Abstract
In this work it is evaluated the influence of mother wavelet in denoising of ultrasonic hepatic signals with Undecimated Wavelet Transform (UWT). First, it is performed a study over simulated ultrasonic signals with different types of mother wavelets and thresholds. The results of this evaluation are applied to ultrasonic hepatic signals. This work shows both the influence of the mother wavelet and the threshold in the final denoised traces.
