Blind signal separation in teleconferencing usingICA mixture model
Un-Min Bae, Te-Won Lee, Soo-Young Lee · Electronics Letters · 2000
An algorithm for separating several sources with fewer sensors in a nonstationary environment is presented. The nonstationary environment is modelled by tracking unmixing matrix classes and the optimal class number is determined using a modified split and merge algorithm. Its usefulness is demonstrated by considering a teleconferencing problem.
