Ask HN: Any computer vision specialist here? I have a problem with OpenTLD

Hello, guys. I have a problem with OpenTLD and tracking. Here is example: https://jpg.wtf/YDVBO/ Like you see, OpenTLD looses tracking point and Kalman filter is "moving away".

Inside I have: OpenTLD + MedianFlow (with LKTracker), after that I correcting result with FERN-features. The output from OpenTLD going trough Kalman filter. The input image (280x280 pixels) to OpenTLD going trough Bilateral filter.

Maybe anyone has any ideas how to improve the result, or where is the best place to ask this question?
