How to use in an online method？

[flyhu2]

Thank you for your work! I would like to apply SmoothNet for facial keypoint smoothing. I am using the pretrained version with a window size of 32, and I implemented it in an online filtering manner, i.e., caching 32 frames of keypoints and taking the output of the last frame as the smoothed result for the current frame. However, the performance does not seem very good. May I ask if the authors adopted an offline filtering approach instead?
