Overview

This is a repository for MASA, a universal instance appearance model for matching any object in any domain. MASA can be added atop of any detection and segmentation models to help them track any objects they have detected.

Introduction

The robust association of the same objects across video frames in complex scenes is crucial for many applications, especially Multiple Object Tracking (MOT). Current methods predominantly rely on labeled domain-specific video datasets, which limits the cross-domain generalization of learned similarity embeddings. We propose MASA, a novel method for robust instance association learning, capable of matching any objects within videos across diverse domains without tracking labels. Leveraging the rich object segmentation from the Segment Anything Model (SAM), MASA learns instance-level correspondence through exhaustive data transformations. We treat the SAM outputs as dense object region proposals and learn to match those regions from a vast image collection. We further design a universal MASA adapter which can work in tandem with foundational segmentation or detection models and enable them to track any detected objects. Those combinations present strong zero-shot tracking ability in complex domains. Extensive tests on multiple challenging MOT and MOTS benchmarks indicate that the proposed method, using only unlabeled static images, achieves even better performance than state-of-the-art methods trained with fully annotated in-domain video sequences, in zero-shot association.

Results on Open-vocabulary MOT Benchmark

• We use the Detic-SwinB as the open-vocabulary detector to provide detections for all our variants.
• MASA-R50: MASA with ResNet-50 backbone. It is a fast and independent model that do not use the backbone features from other detection or segmentation foundation models. It needs to be used with any other detectors. It is trained in the same way as other masa variants.

Demo Run

Preparation

1. First, create a folder named saved_models in the root directory of the project. Then, download the following models and put them in the saved_models folder.

   a). Download the MASA-GroundingDINO and put it in saved_models/masa_models/gdino_masa.pth folder.

2. (Optional) Second, download the demo videos and put them in the demo folder. We provide two short videos for testing (minions_rush_out.mp4 and giraffe_short.mp4). You can download more demo videos here.

3. Finally, create the demo_outputs folder in the root directory of the project to save the output videos.

Demo 1:

python demo/video_demo_with_text.py demo/minions_rush_out.mp4 --out demo_outputs/minions_rush_out_outputs.mp4 --masa_config configs/masa-gdino/masa_gdino_swinb_inference.py --masa_checkpoint saved_models/masa_models/gdino_masa.pth --texts "yellow_minions" --score-thr 0.2 --unified --show_fps

• --texts: the object class you want to track. If there are multiple classes, separate them like this: "giraffe . lion . zebra". Please note that texts option is currently only available for the open-vocabulary detectors.
• --out: the output video path.
• --score-thr: the threshold for the visualize object confidence.
• --detector_type: the detector type. We support mmdet and yolo-world (soon).
• --unified: whether to use the unified model.
• --no-post: not to use the postprocessing. Default is to use, adding this will disable it. The postprocessing uses masa tracking to reduce the jittering effect caused by the detector.
• --show_fps: whether to show the fps.
• --sam_mask: whether to visualize the mask results generated by SAM.
• --fp16: whether to use fp16 mode.

The hyperparameters of the tracker can be found in corresponding config files such as configs/masa-gdino/masa_gdino_swinb_inference.py. Current ones are set for the best performance on the demo video. You can adjust them according to your own video and needs.

Demo 2:

Download the sora_fish_10s.mp4 and put it in the demo folder.

python demo/video_demo_with_text.py demo/sora_fish_10s.mp4 --out demo_outputs/msora_fish_10s_outputs.mp4 --masa_config configs/masa-gdino/masa_gdino_swinb_inference.py --masa_checkpoint saved_models/masa_models/gdino_masa.pth --texts "fish"  --score-thr 0.1 --unified --show_fps

Demo 3 (with Mask):

a). Download SAM-H weights and put it in saved_models/pretrain_weights/sam_vit_h_4b8939.pth folder.

b). Download the carton_kangaroo_dance.mp4 and put it in the demo folder.

python demo/video_demo_with_text.py demo/carton_kangaroo_dance.mp4 --out demo_outputs/carton_kangaroo_dance_outputs.mp4 --masa_config configs/masa-gdino/masa_gdino_swinb_inference.py --masa_checkpoint saved_models/masa_models/gdino_masa.pth --texts "kangaroo" --score-thr 0.4 --unified --show_fps --sam_mask

Plug-and-Play MASA Tracker

You can directly use any detector along with our different MASA variants to track any object.

Demo with YOLOX detector:

Here is an example of how to use the MASA adapter with the YoloX detector pretrained on COCO.

Download the YoloX COCO detector weights from here and put it in the saved_models/pretrain_weights/yolox_x_8x8_300e_coco_20211126_140254-1ef88d67.pth.

Roadmaps:

Here are some of the things we are working on and please let us know if you have any suggestions or requests:

• [] Release the unified model with YOLO-world detector for fast open-vocabulary tracking.
• [] Release the training code for turning your own detector to a strong tracker on unlabeled images from your domain.
• [x] Release the plug-and-play MASA model, compatible any detection and segmentation models.
• [x] Release the benchmark testing on TAO and BDD100K.
• [x] Release pre-trained unified models in the paper and the inference demo code.

Limitations:

MASA is a universal instance appearance model that can be added atop of any detection and segmentation models to help them track any objects they have detected. However, there are still some limitations:

• MASA does not have the ability to track objects that are not detected by the detector.
• MASA cannot fix inconsistent detections from the detector. If the detector produces inconsistent detections on different video frames, results look flickering.
• MASA trains on pure unlabeled static images and may not work well in some scenarios with heavy occlusions and noisy detections. Directly using ROI Align for the noisy or occluded objects yields suboptimal features for occlusion handling. We are working on improving the tracking performance in such scenarios.
