 ## Pretrained object detection models
 
 You will have to download the pretrained weights for the neural-network models.

 * There are some variations in implementations as compared to what appeared in papers of `SORT` and `IoU Tracker`.
 * In case you find any bugs in the algorithm, I will be happy to accept your pull request or you can create an issue to point it out.
