摘要
•A posterior Wiener filtering was applied to the FFR extraction, as well as sub-band optimal weighted averaging and Median averaging method.•Wiener achieved the best performance in improving FFR quality and experiment efficiency, thus it is the most suitable method for FFR preprocessing.•Comprehensive and quantitative quality indices were described to evaluate FFR qualities.
