From: Independent vector analysis using subband and subspace nonlinearity
Subband correlation matrices and corresponding eigenvalues. The first, second, and third rows are examples for high, middle, and low-frequency subbands, respectively, subband size is 100. The first and the second columns are correlation matrices for one estimated source when IVA begins and ends, correlation matrices are reversed upside down for visualization. The third column visualizes the five largest eigenvalues of the correlation matrices.
