Deep Sort with PyTorch

Latest Update(07-22)

Changes

bug fix (Thanks @JieChen91 and @yingsen1 for bug reporting).
using batch for feature extracting for each frame, which lead to a small speed up.
code improvement.

Futher improvement direction

Train detector on specific dataset rather than the official one.
Retrain REID model on pedestrain dataset for better performance.
Replace YOLOv3 detector with advanced ones.

Any contributions to this repository is welcome!

Introduction

This is an implement of MOT tracking algorithm deep sort. Deep sort is basicly the same with sort but added a CNN model to extract features in image of human part bounded by a detector. This CNN model is indeed a RE-ID model and the detector used in PAPER is FasterRCNN , and the original source code is HERE.
However in original code, the CNN model is implemented with tensorflow, which I'm not familier with. SO I re-implemented the CNN feature extraction model with PyTorch, and changed the CNN model a little bit. Also, I use YOLOv3 to generate bboxes instead of FasterRCNN.

Dependencies
