Can this model tracking people or hand movement about openpose HOT 13 CLOSED

@heurainbow Are there any progress in your multi-person pose tracker? Do you implement it base on the key points from openpose?

from openpose.

It'd be an extra component, that can be enabled (slower but with temporary information) or disabled (to keep the current OpenPose behavior)

from openpose.

Not for now, but we are planing to (as a LONG-term goal).

We have them both as pending extensions in our wait-list (hands should be added within 1-2 months, tracking we do not have an idea yet).

There are some methods for tracking, in case you are interested. You can take a look to #15.

Let me know if you have any other question.

Thank you for your reply！

I am going to implement a multi-person pose tracker. I find the hand tracker already implemented is quite helpful. However, I wonder how to acquire (or update) frame ID in class HandDetector. Can I simply make mCurrentId++ when calling updateTracker()? I am not familiar with the multi-threading framework, and I am not sure if this is the right way. @gineshidalgo99

The hand tracker is not finished yet, but anyway it is meant for different purposes than tracking the same person across frames.
I think the easiest way is to get the frame ID is by checking the (include/core/) Datum that is shared among the multi-threads. In particular, its id field. Since you will have to use the shared Datum anyway, using that ID should be the easiest. @heurainbow

@gineshidalgo99 I wonder how a webcam producer or a video producer keep the frame order sequentially in a multi-gpu case. Since each frame is processed by one gpu, there is no guarantee that each frame is processed in order. But the gui does show images in order and I couldn't find the reason in the code.

There is a internal buffer to keep the order

@gineshidalgo99 If possible, please show me which file or code I should refer to, and please give me a brief explanation.

from openpose.

This is the file, it simply uses the Datum ID to sort the frames

@gineshidalgo99 what methods for tracking did you look at?

from openpose.

@seovchinnikov We are currently working in an expensive but accurate body recognition algorithm and in a basic bust fast LK tracking algorithm. We are trying to add them by the end of the year. Thanks

@gineshidalgo99 thank you,
As far as I understand, will body recognition algorithm' be based on basic body keypoints detector or will it be inderpendent end-to-end part to complement openpose library (smth like https://github.com/bendidi/Tracking-with-darkflow)?
