Important note

FastTrack v5.x.y is not fully retro compatible with FastTrack v4.x.y. Old analysis can be opened and reviewed but if re-tracked, the parameters have to be adjusted!

The cost function can now be fine-tuned more accurately due to the correction of a conversion error between the user interface and the backend leading to better tracking accuracy in some cases.

Equivalence between old and new parameters can de derivated as:

  • new_normDist = old_nomDist/weight
  • new_normAngle = old_normAngle/((1-weight)*60)

New tuning of these two parameters is highly recommended:

  • Set the normalization distance as the typical displacement of an object in pixels.
  • Set the normalization angle as the typical reorientation of an object in degrees.
  • Increase the normalization distance or decrease the normalization angle to be more sensitive to the reorientation. Decrease the normalization distance or increase the normalization angle to be more sensitive to the displacement.

Major changes

  • Fixed error in the normalization angle parameter
  • Removed deprecated weight tracking parameter.
