## Practical Server Side Detection

### Introduction

* In recent years, the object detection task in image has been widely concerned by academia and industry. ResNet50vd pretraining model based on SSLD distillation program training in [PaddleClas](https://github.com/PaddlePaddle/PaddleClas) (Top1 on ImageNet1k verification set) Acc is 82.39%), combined with the rich operator of PaddleDetection, PaddlePaddle provides a practical server side detection scheme PSS-DET(Practical Server Side Detection). Based on COCO2017 object detection dataset, V100 single gpu prediction speed is 61FPS, COCO mAP can reach 41.2%.
