UniquenessOffsetΒΆ

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
