What is wavelet decomposition level?

Based on Ref. [20], the decomposition level for each wavelet family is set to 1. Compared to other wavelet families the coiflet wavelets clearly show the patterns of the t–f image in H, V, and D images rather than the other wavelets, respectively.

How do you choose a wavelet decomposition level?

Theoretically, the maximum decomposition level (M) can be calculated as: M = log2 (N), where N is the series length. When conducting a wavelet-based ANN model, it needs to determine the most suitable decomposition level from 1 to M.

What is decomposition level?

The decomposition level is a matter of the number and type of components which can be grouped together, the decomposition extent is a matter of when, for example, a normally closed path or parallel stream warrants separate treatment.

What determines the level of decomposition?

The rate of decomposition is governed by three sets of factors—the physical environment (temperature, moisture and soil properties), the quantity and quality of the dead material available to decomposers, and the nature of the microbial community itself.
