MSE. IS Figure 2.8 First step experimental results: Choice of the number of analysis levels. (a) Gain in SNRglo. (b) Gain in SNRseg. (c) MSE. (d) IS. If we consider the results in terms of gain in segmental SNR, the more the SNR of the noised signal (SNRin) is negative, the more the gain obtained by increasing the number of analysis levels of the wavelet transform is significant. Good results have been found to be obtained using ten analysis levels. The three other criteria (global SNR, MSE and IS distortion measure) lead to the same conclusion.
