The iterative alternating optimization (IAO) algorithm is proposed to optimize the coefficients of the (frequency domain/ spectral) general design two-channel bi-orthogonal graph filter banks (2c-BiO-graph-FB). Its basic idea is iteratively and alternatingly optimizing part of the coefficients while...
