Hi.
Does any one knows about the ransac algorithm ?
I want to sort datsa that are supposed to be a straight line despite
some outlier points..
If i know where to find some webbook et something else, i would be
pleased.
Thank you.

Really ? Nice suggestion !
I am trying to find some more accurate documents if anyone would have
already made such an web search.

You won't find any ready-to-use code because RANSAC is quite simple in
its form but requires to set arbitrary thresholds which are very
application dependant. If all you want to do is fit a straight line when
there are some outliers robust regression (use google) methods (like
minimizing the median error instead of the mean error or applying a
running median filter on the data first) are easier to implement because
less parameter tuning is required.
