You first select the color of the blemish, then select the skin tone, and it colors the former to match the latter, along with smoothing if specified. The coverup keys on color, so the color of the blemish must be distinct enough from normal skintone for DCU to isolate it.

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector. It also works on any specified dimension of...
