Seismic Random Noise Denoising Using Mini-Batch Multivariate Variational Mode Decomposition

Figure 3

Bivariate signal: each has three components and a certain percentage of Gaussian noise. (a) The bottom of left column consists of three different tones (the top three signals in left column) and a certain percentage of Gaussian noise (the fourth signal in left column). (b) The bottom of right column also consists of three different tones and a certain percentage of Gaussian noise.
