mio::FilterRate Class Reference

Detailed Description

Rate of change filter.

Calculate the change rate (ie: slope) between two points, if it is above a user given value, reject the point. It takes the following arguments:

  • MIN: minimum permissible rate of change (per seconds, optional);
  • MAX: either the absolute value of the maximum permissible rate of change (per seconds) if no other argument is provided, or maximum permissible rate of change (per seconds) if a MIN was provided.
  • METHOD: which points are taken into account when computing the rate of change (optional, default is LEFT). It can be either one of:
    • LEFT: looking for the rate of change on the left of the current point, ie between the last valid point and the current one (default);
    • RIGHT: looking for the rate of change on the right of the current point, ie between the current point and the next valid one;
    • LEFT_AND_RIGHT: excluding a point if the rate of change exceeds MAX or MIN both on the left and on the right of the current point;
    • LEFT_OR_RIGHT: excluding a point if the rate of change exceeds MAX or MIN either on the left or on the right of the current point;

So depending if MIN and MAX were provided or only MAX, every point where the local rate of change is outside [ MIN , MAX] or every point outside [ -MAX , MAX] is rejected.

TA::filter1 = rate
TA::arg1::MIN = -0.01
TA::arg1::MAX = 0.015
