WebJan 26, 2024 · It is shown that the combination of minimaxi and bior2.2 (minimaxi-bior2.2) has higher Acc cv than the combination of other thresholds and wavelet functions . Figure 4 shows that DL = 6 is the best DL for WTD (minimaxi-bior2.2) of Raman spectral data. Therefore, minimaxi-bior2.2 and DL = 6 were selected as the optimal wavelet … WebDec 29, 2024 · Moreover, bior2.6 wavelet produced the best SNR on all decomposition scales, followed in turn by bior2.4, and bior2.2. Therefore, when the length of low-pass decomposition filter sequence falls in a certain range, the SNR is proportional to the sequence length. If the sequence is excessively long, the SNR cannot be further improved.
