Functional MRI Time Series Generation via Wavelet-Based Image Transform and Spectral Flow Matching for Brain Disorder Identification

In three linesDSFM (Dual-Spectral Flow Matching) generates synthetic fMRI time series by combining discrete wavelet transform (DWT) and discrete cosine transform (DCT) with spectral flow matching. The model captures non-stationarity and spatiotemporal dynamics of BOLD signals to improve brain network classification.
