Unconstrained Wiener synthetic discriminant function arithmetic research

The constrained condition of output correlation peak value is removed in MACE matched filter, and the correlation criterion is redefined. The distortion invariant synthetic discriminant function obtained is Wiener filtering function based on correlation criterion to be defined, the filter's sensitivity to input noise and image distortion is reduced. The computer simulation result shows that this kind of synthetic filter can enhance the distortion tolerance and the ability of resisting noise.
