EMCD-derived correlation (a) and Pearson correlation of original time series and feature series (b) between visual motion saliency feature curve and fMRI time series. EMCD-derived correlation (c) and Pearson correlation (d) between logarithm audio signal energy feature curve and fMRI time series. The color bar is at the bottom. The arrows in the same colors highlighted some brain regions with significant differences between the two methods in (a) and (b), as well as in (c) and (d). The correlation is much stronger between the visual motion saliency feature and brain regions for motion perception, including MT and MST (black arrows), while negative correlation was exposed for insular and precuneus (red arrows and blue bubbles in (a)). When comparing with logarithm audio signal energy feature, insular and paracingulate exhibited strong correlation (c). The corresponding Pearson correlation results shown in (b) and (d) could not reveal the differences.
