摘要: | We empirically show that there exists a better threshold than the minimax or universal estimators for resolution cutoff J in the wavelet transform. Tests are conducted on de-noising both 1-D and 2-D signals to which Gaussian white noise is added. Donoho (1992) and Donoho and Johnstone (1994, 1995) proposed the Waveshrink method for reconstructing an unknown function from input data corrupted by Ga... |
