Detected face landmarks are rounded to integer

Is it the correct behavior?

I just traced the code, looks like the landmarks are maximum of 64x64 heatmap.
So the detected landmarks should be on the heatmap grid.

@LexSong Yes, you are right. You can probably keep them real but this will not matter to much in practice.

@1adrianb I just tried the landmark detector on a video, and the "rounding" landmarks are jumping around between video frames. The movement is not smooth. I will add a smooth filter to solve my issue. Thanks for your help

@LexSong Yes, smoothing should defenitly help. Is the "jump" significant? In the video that I generated the next frame was initialised with the previous prediction (the bbox of the prediction) which made the results more stable than using a detector. I don't know however if it we be useful also in your case.
Also, if time is not an issue you can run it twice on the same frame (first using the detected bbox and then by running it using the newly obtained bbox).

@1adrianb Thanks, I'll do more experiments
