Shaky/Jittery Tracking of 3D objects with Vuforia 3 and Unity 4.6

I am developing an app which requires simultaneous tracking of multiple image targets. I am using Vuforia SDK version 3.0.9 with Unity 3D version 4.6.1. my problem is that my 3D objects are shaking(vibrating/jittery) in the scene. I am using AUTO_FOCUS_CONTINUOUS with camera device. Also my image targets are 5 star rated.

I have seen many posts on the same topic including this but none was able to solve my problem. Solutions described in above post either work with only old versions of Vuforia or work for only single object when Vuforia is tracking multiple objects simultaneously. I understand that low pass filtering of pose matrix is the only way to go, but I am not sure how do I implement that in the version of Vuforia SDK I am using.

Or should I downgrade to an older version.. please give some pointers.
