Abstract:

A new initialization algorithm for blind separation of images is proposed based on curvelet sparse representation. A mixed matrix can be estimated by estimating the center of received signals. This method can
improve convergence and effectively avoid falling into local minima. Simulation results show that the proposed
algorithm can achieve better performance for blind source separation of images.

Key words: blind source separation, sparse representation, Curvelet transform, initialization
