Davood Fattahi, Behrooz Nasihatkon, Reza Boostani

Abstract: Highlights•The CSP algorithm is described as a sequential procedure of spatial filter estimation.•Generalized version of the CSP is introduced.•The general framework is used for simultaneously spatio-spectral filters estimation.•From the proposed generalization, two new spatial and spatio-spectral filter estimation schemes are introduced.•The proposed methods and similar algorithms are compared and implemented.•Improving in classification accuracy and stability is shown.
