Wiener-like correlation filters

We introduce a new, to our knowledge, design for a Wiener-Like correlation filter, which consists of cascading a phase-only filter (POF) with a photor eactive Wiener-like filter. Its performance is compared with that of the PO F and the Wiener correlation filter (WCF). Correlation results show that fo r intermediate and higher levels of noise this correlation filter has a pea k-to-noise ratio that is larger than that of either the POF or the WCF whil e still preserving a correlation peak that is almost as high as that of the POF.
