TSD

News: We reimplement the TSD algorithm based on the MMDetection framework.

1st place solutions for openimage 2019 (https://arxiv.org/abs/2003.07557)

Introduction

The installation of MMDetection can be found from the official github(https://github.com/open-mmlab/mmdetection)

TSD is a plugin detector head which is friendly to any anchor-based two stage detectors (Faster RCNN, Mask RCNN and so on).

Overview

Changelog

V1.0: We firstly reimplement the experiments based on Faster RCNN with Resnet families.

The SharedFCBBoxHead is used as the sibling head.

The corresponding configuration can be found in (faster_rcnn_r50_fpn_TSD_1x.py, faster_rcnn_r101_fpn_TSD_1x.py, faster_rcnn_r152_fpn_TSD_1x.py)

Tips:

  1. LR can be set to base_lr*total_batch (base_lr=0.00125, 0.04 = 0.00125*32 in our experiments.)
  2. An external epoch can be used to perform warmup. (base_lr will be incresed to LR in the first epoch)

Experiments

Reimplemented methods and backbones are shown in the below table. It's based on the Faster RCNN with FPN. More backbones and experiments are underway.

Backbone TSD AP AP_0.5 AP_0.75 AP_s AP_m AP_l Download
ResNet50 36.2 58.1 39.0 21.8 39.9 46.1
ResNet50 40.9 61.9 44.4 24.2 44.4 54.0 model
ResNet101 38.9 60.6 42.4 22.3 43.6 50.6
ResNet101 42.3 63.1 45.9 25.1 46.3 56.5 model
ResNet152 40.5 62.1 44.5 24.6 45.0 51.8
ResNet152 43.7 64.5 47.6 26.1 48.0 57.5 model

TBD

We will continue to update the pretrained models of some heavy backbones.
