Shift points in space and time, but scale them only in space.
Sometimes dots have mutliple points due to an
error in the device. This filter replaces lines where the maximum
distance of points in that line is lower than a threshold.
Sometimes users get points at the end of lines
which they did not want to make. Those points have a significant change of
direction. This method removes points at the end that would lead to
a change of direction above a threshold.
Sometimes hardware makes points when the user does not
want to make points. A characteristic of those points is sometimes a very
high speed. You can modify the minimum time delta two points should have.
Apply the Douglas-Peucker algorithm to get
rid of points that seem to be not much different from other points.
Space points equidistant in time.
This might be much.
