# UniquenessOffset¶

Adds a constant offset to $$C_{1st}$$ and $$C_{2nd}$$ before the evaluation of the UniquenessRatio. Adding a constant offset will avoid noisy uniqueness values in low contrast areas and increase the likelihood of filtering out pixels in low contrast areas by biasing the ratio $$\frac{C_{1st}}{C_{2nd}}$$ towards 1.

Format

 Number An integer specifying the uniqueness offset in gray values.
