Figure 1From: Time-Frequency Data Reduction for Event Related Potentials: Combining Principal Component Analysis and Matching Pursuit A comparison of the principal components (PCA), Gabor logons extracted from the principal components (PCA-Gabor) and Gabor logons extracted by Simultaneous Matching Pursuit using a Gabor dictionary (SMP-Gabor) from two simulated datasets (3-logons with no noise and 3-logons with noise).
