Highlights

  • Supports tracking algorithms including multi-object tracking (MOT) algorithms SORT, DeepSORT, StrongSORT, OCSORT, ByteTrack, QDTrack, and video instance segmentation (VIS) algorithm MaskTrackRCNN, Mask2Former-VIS.
  • Support ViTDet
  • Supports inference and evaluation of multimodal algorithms GLIP and XDecoder, and also supports datasets such as COCO semantic segmentation, COCO Caption, ADE20k general segmentation, and RefCOCO. GLIP fine-tuning will be supported in the future.
  • Provides a gradio demo for image type tasks of MMDetection, making it easy for users to experience.

Exciting Features

GLIP inference and evaluation

s multimodal vision algorithms continue to evolve, MMDetection has also supported such algorithms. This section demonstrates how to use the demo and eval scripts corresponding to multimodal algorithms using the GLIP algorithm and model as the example. Moreover, MMDetection integrated a gradio_demo project, which allows developers to quickly play with all image input tasks in MMDetection on their local devices. Check the document for more details.

Preparation

Please first make sure that you have the correct dependencies installed:

# if source
pip install -r requirements/multimodal.txt

# if wheel
mim install mmdet[multimodal]

MMDetection has already implemented GLIP algorithms and provided the weights, you can download directly from urls:

cd mmdetection
wget https://download.openmmlab.com/mmdetection/v3.0/glip/glip_tiny_a_mmdet-b3654169.pth

Inference

Once the model is successfully downloaded, you can use the demo/image_demo.py script to run the inference.

python demo/image_demo.py demo/demo.jpg glip_tiny_a_mmdet-b3654169.pth --texts bench

Demo result will be similar to this:

If users would like to detect multiple targets, please declare them in the format of xx . xx . after the --texts.

python demo/image_demo.py demo/demo.jpg glip_tiny_a_mmdet-b3654169.pth --texts 'bench . car .'

And the result will be like this one:

You can also use a sentence as the input prompt for the --texts field, for example:

python demo/image_demo.py demo/demo.jpg glip_tiny_a_mmdet-b3654169.pth --texts 'There are a lot of cars here.'

The result will be similar to this:

Evaluation

The GLIP implementation in MMDetection does not have any performance degradation, our benchmark is as follows:

Model official mAP mmdet mAP
glip_A_Swin_T_O365.yaml 42.9 43.0
glip_Swin_T_O365.yaml 44.9 44.9
glip_Swin_L.yaml 51.4 51.3

Users can use the test script we provided to run evaluation as well. Here is a basic example:

# 1 gpu
python tools/test.py configs/glip/glip_atss_swin-t_fpn_dyhead_pretrain_obj365.py glip_tiny_a_mmdet-b3654169.pth

# 8 GPU
./tools/dist_test.sh configs/glip/glip_atss_swin-t_fpn_dyhead_pretrain_obj365.py glip_tiny_a_mmdet-b3654169.pth 8

The result will be similar to this:

Prepare your dataset according to the docs.

Test Command

Since semantic segmentation is a pixel-level task, we don't need to use a threshold to filter out low-confidence predictions. So we set model.test_cfg.use_thr_for_mc=False in the test command.

Note:

  1. If you set the scale of Resize to (1024, 512), the result will be 57.69.
  2. text mode is the RefCoCoDataset parameter in MMDetection, it determines the texts loaded to the data list. It can be set to select_first, original, concat and random.
    • select_first: select the first text in the text list as the description to an instance.
    • original: use all texts in the text list as the description to an instance.
    • concat: concatenate all texts in the text list as the description to an instance.
    • random: randomly select one text in the text list as the description to an instance, usually used for training.

Image Caption on COCO2014

Prepare your dataset according to the docs.

Before testing, you need to install jdk 1.8, otherwise it will prompt that java does not exist during the evaluation process
