-## 二、算法介绍
-
-PP-Tracking 支持单镜头跟踪(MOT)和跨镜头跟踪(MTMCT)两种模式。
-- 单镜头跟踪同时支持**FairMOT**和**DeepSORT**两种多目标跟踪算法，跨镜头跟踪只支持**DeepSORT**算法。
-- 单镜头跟踪的功能包括行人跟踪、车辆跟踪、多类别跟踪、小目标跟踪以及流量统计，模型主要是基于FairMOT进行优化，实现了实时跟踪的效果，同时基于不同应用场景提供了针对性的预训练模型。
-- DeepSORT算法方案(包括跨镜头跟踪用到的DeepSORT)，选用的检测器是PaddleDetection自研的高性能检测模型[PP-YOLOv2](../../ppyolo/)和轻量级特色检测模型[PP-PicoDet](../../picodet/)，选用的ReID模型是PaddleClas自研的超轻量骨干网络模型[PP-LCNet](https://github.com/PaddlePaddle/PaddleClas/blob/release/2.3/docs/zh_CN/models/PP-LCNet.md)

-**注意：**
-1. 模型预测速度的设备为**NVIDIA Jetson Xavier NX**，速度为**TensorRT FP16**速度，测试环境为CUDA 10.2、JETPACK 4.5.1、TensorRT 7.1。
-2. 模型权重是指使用PaddleDetection训练完直接保存的权重，更多跟踪模型权重请参考[多目标跟踪模型库](../../configs/mot/README.md#模型库)去下载，也可按照相应模型配置文件去训练。
-3. 预测部署模型是指导出后的前向参数的模型，因为PP-Tracking项目的部署过程中只需要前向参数，可根据[多目标跟踪模型库](../../configs/mot/README.md#模型库)去下载并导出，也可按照相应模型配置文件去训练并导出。导出后的模型文件夹应包括`infer_cfg.yml`、`model.pdiparams`、`model.pdiparams.info`和`model.pdmodel`四个文件，一般会将它们以tar格式打包。
