Low Fps

[shakibmehr]

hi
This project can track a relatively small object (about 15 pixels) with an update rate of 2.5 seconds?
If so, with what settings?

[Nuzhny007]

Hm, I don't know. May be you have some example?
If you can't show a natural video then it can be generated: draw on frame some object.
And the second question: video with low fps or detector with low fps?

You can use background subtraction but analyze not every frame. Do you know minimal objects speed? 10 or 20 pixels in second? Drop 20-30-50 frames and analyze only key frames and interpolate in the middle.

The minimum speed is 10 pixels.
How can I do the interpolation?
update rate 2.5 per second
Is it possible to send me the program you used to create this video?

Hi!
Sorry for the long answer.

1. Update this project to a last version: make && make install
2. Build this project: https://github.com/Nuzhny007/slow_motion_detector

They works just not without frames interpolation. coming son...

I;m updating slow_motion_detector with trajectory interpolation

这个项目有kcf算法吗？yolo+kcf

[Nuzhny007]

Yes. Not only kcf but any Visual tracker from OpenCV
