Segment and Track Anything (SAM-Track)

Online Demo:

Tutorial: tutorial-v1.5 (Text), tutorial-v1.0 (Click & Brush)

Segment and Track Anything is an open-source project that focuses on the segmentation and tracking of any objects in videos, utilizing both automatic and interactive methods. The primary algorithms utilized include the SAM (Segment Anything Models) for automatic/interactive key-frame segmentation and the DeAOT (Decoupling features in Associating Objects with Transformers) (NeurIPS2022) for efficient multi-object tracking and propagation. The SAM-Track pipeline enables dynamic and automatic detection and segmentation of new objects by SAM, while DeAOT is responsible for tracking all identified objects.

📢New Features

• [2023/4/29] We have added advanced arguments for AOT-L: long_term_memory_gap and max_len_long_term.

  • long_term_memory_gap controls the frequency at which the AOT model adds new reference frames to its long-term memory. During mask propagation, AOT matches the current frame with the reference frames stored in the long-term memory.
  • Setting the gap value to a proper value helps to obtain better performance. To avoid memory explosion in long videos, we set a max_len_long_term value for the long-term memory storage, i.e. when the number of memory frames reaches the max_len_long_term value, the oldest memory frame will be discarded and a new frame will be added.

• [2023/4/26] Interactive WebUI 1.5-Version: We have added new features based on Interactive WebUI-1.0 Version.

  • We have added a new form of interactivity—text prompts—to SAMTrack.
  • From now on, multiple objects that need to be tracked can be interactively added.
  • Check out tutorial for Interactive WebUI 1.5-Version. More demos will be released in the next few days.

• [2023/4/26] Image-Sequence input: The WebUI now has a new feature that allows for input of image sequences, which can be used to test video segmentation datasets. Get started with the tutorial for Image-Sequence input.

• [2023/4/25] Online Demo: You can easily use SAMTrack in Colab for visual tracking tasks.

• [2023/4/23] Interactive WebUI: We have introduced a new WebUI that allows interactive user segmentation through strokes and clicks. Feel free to explore and have fun with the tutorial!

🔥Demos

This video showcases the segmentation and tracking capabilities of SAM-Track in various scenarios, such as street views, AR, cells, animations, aerial shots, and more.

📆TODO

• Colab notebook: Completed on April 25th, 2023.
• 1.0-Version Interactive WebUI: Completed on April 23rd, 2023.
  • We will create a feature that enables users to interactively modify the mask for the initial video frame according to their needs. The interactive segmentation capabilities of Segment-and-Track-Anything is demonstrated in Demo1 and Demo2.
  • Bilibili Video Link: Demo1, Demo2.
• 1.5-Version Interactive WebUI: Completed on April 26th, 2023.
  • We will develop a function that allows interactive modification of multi-object masks for the first frame of a video. This function will be based on Version 1.0.
  • Furthermore, we plan to include text prompts as an additional form of interaction.
• 2.x-Version Interactive WebUI
  • In version 2.x, the segmentation model will offer two options: SAM and SEEM.
  • We will develop a new function where the fixed-category object detection result can be displayed as a prompt.

Demo1 showcases SAM-Track's ability to interactively segment and track individual objects. The user specified that SAM-Track tracked a man playing street basketball.

Demo2 showcases SAM-Track's ability to interactively add specified objects for tracking.The user customized the addition of objects to be tracked on top of the segmentation of everything in the scene using SAM-Track.

💻Getting Started

📑Requirements

The Segment-Anything repository has been cloned and renamed as sam, and the aot-benchmark repository has been cloned and renamed as aot.

Please check the dependency requirements in SAM and DeAOT.

The implementation is tested under python 3.9, as well as pytorch 1.10 and torchvision 0.11. We recommend equivalent or higher pytorch version.

Use the install.sh to install the necessary libs for SAM-Track

bash script/install.sh

⭐Model Preparation

Download SAM model to ckpt, the default model is SAM-VIT-B (sam_vit_b_01ec64.pth).

Download DeAOT/AOT model to ckpt, the default model is R50-DeAOT-L (R50_DeAOTL_PRE_YTB_DAV.pth).

Download Grounding-Dino model to ckpt, the default model is GroundingDINO-T (groundingdino_swint_ogc).

You can download the default weights using the command line as shown below.

bash script/download_ckpt.sh

❤️Run Demo

• The video to be processed can be put in ./assets.
• Then run demo.ipynb step by step to generate results.
• The results will be saved as masks for each frame and a gif file for visualization.

The arguments for SAM-Track, DeAOT and SAM can be manually modified in model_args.py for purpose of using other models or controling the behavior of each model.

💪WebUI App

Our user-friendly visual interface allows you to easily obtain the results of your experiments. Simply initiate it using the command line.

python app.py

Users can upload the video directly on the UI and use SegTracker to automatically/interactively track objects within that video. We use a video of a man playing basketball as an example.

SegTracker-Parameters:

• aot_model: used to select which version of DeAOT/AOT to use for tracking and propagation.
• sam_gap: used to control how often SAM is used to add newly appearing objects at specified frame intervals. Increase to decrease the frequency of discovering new targets, but significantly improve speed of inference.
• points_per_side: used to control the number of points per side used for generating masks by sampling a grid over the image. Increasing the size enhances the ability to detect small objects, but larger targets may be segmented into finer granularity.
• max_obj_num: used to limit the maximum number of objects that SAM-Track can detect and track. A larger number of objects necessitates a greater utilization of memory, with approximately 16GB of memory capable of processing a maximum of 255 objects.

Usage: To see the details, please refer to the tutorial for 1.0-Version WebUI.
