Hi, I have q question regarding the detection files from YOLO, Fast-RCNN. How was it generated?
As for example in det_yolo3.txt,
1,-1,1094.277,257.304,63.898,62.347,0.400,-1,-1,-1, what does -1 signify?
I am guessing that "1" signifies the trackID and the floating numbers following "1" signify the positions of the bounding box and the confidence score. Where is the frame number, class?
I have trained my dataset on yolo and was hoping to use the code for tracking. Your help in this regard is really appreciated

HI, I have the same issue.

So basically, you train a siamese NN and get a model.pt file.
Then you generated object bbox information (txt) produced from object detection model, replace the output with det/*txt.
Finally modify ckpt path in test_on_video.py, am I right?

I'm not quite sure how you train and make prediction with this model on a custom data.

The first digit is frame number
The second digit is the object ID. -1 means it is not assigned yet. It will be assigned after executing deep_sort
The four floating numbers are the box coordinate and size
The 0.400 is the confidence score.
Don't bother about the last triple -1.
