“…The matrix W W T , dependent only on the particular wavelet system and temporal grid, emerges as a key indicator of noise structure in the wavelet domain, providing the mechanism for noise distribution among resolution levels. Correlation dependent thresholding [2], designed for biorthogonal wavelet systems, C118 applies a modified universal threshold to coefficient γ jk…”

“…Implementaciones de este tipo se pueden encontrar en algunos trabajos teóricos como [121,122], y de manera más reciente en aplicaciones relacionadas fundamentalmente con el procesado de imágenes [123,124]. En la bibliografía referente a ultrasonidos, el uso más destacado de este tipo de implementaciones se sitúa en el ámbito de la reducción de ruido en señales doppler utilizadas en diagnóstico médico [125][126][127].…”
