Hi Jack!, I was testing proposed by colleagues, and it works, I removed the noise, not yet determined what happens, but it becomes stable, at least the stable axes can provide data, but I keep trying, I've worked with opencv and works without problems, also gridflow is amazing ... Now, the moment I'm testing this and yours Jack, I like plot, but remember the grid view, I have seen in the help or the site of Pd. In work, the grid blue and red dots.
What else could be proposed?
