Tracking Any Point (TAP)

Welcome to the official Google Deepmind repository for Tracking Any Point (TAP), home of the TAP-Vid and TAPVid-3D Datasets, our top-performing TAPIR model, and our RoboTAP extension.

TAP-Vid is a benchmark for models that perform this task, with a collection of ground-truth points for both real and synthetic videos.
TAPIR is a two-stage algorithm which employs two stages: 1) a matching stage, which independently locates a suitable candidate point match for the query point on every other frame, and (2) a refinement stage, which updates both the trajectory and query features based on local correlations. The resulting model is fast and surpasses all prior methods by a significant margin on the TAP-Vid benchmark.
RoboTAP is a system which utilizes TAPIR point tracks to execute robotics manipulation tasks through efficient imitation in the real world. It also includes a dataset with ground-truth points annotated on real robotics manipulation videos.
BootsTAP (or Bootstrapped Training for TAP) uses a large dataset of unlabeled, real-world video to improve tracking accuracy. Specifically, the model is trained to give consistent predictions across different spatial transformations and corruptions of the video, as well as different choices of the query points. We apply it to TAPIR to create BootsTAPIR, which is architecturally similar to TAPIR but substantially outperforms it on TAP-Vid.
TAPVid-3D is a benchmark and set of metrics for models that perform the 3D point tracking task. The benchmark contains 1M+ computed ground-truth trajectories on 4,000+ real-world videos.

This repository contains the following:

TAPIR / BootsTAPIR Demos for both online colab demo and offline real-time demo by cloning this repo
TAP-Vid Benchmark for both evaluation dataset and evaluation metrics
RoboTAP Benchmark for both evaluation dataset and point track based clustering code
TAPVid-3D Benchmark for the evaluation metrics and sample evaluation code for the TAPVid-3D benchmark.
Checkpoints for TAP-Net (the baseline presented in the TAP-Vid paper), TAPIR and BootsTAPIR pre-trained model weights in both Jax and PyTorch
Instructions for training TAP-Net (the baseline presented in the TAP-Vid paper) and TAPIR on Kubric

Demos

The simplest way to run TAPIR / BootsTAPIR is to use our colab demos online. You can also clone this repo and run on your own hardware, including a real-time demo.

Colab Demo

You can run colab demos to see how TAPIR works. You can also upload your own video and try point tracking with TAPIR. We provide a few colab demos:

Standard TAPIR: This is the most powerful TAPIR / BootsTAPIR model that runs on a whole video at once. We mainly report the results of this model in the paper.
Online TAPIR: This is the sequential causal TAPIR / BootsTAPIR model that allows for online tracking on points, which can be run in real-time on a GPU platform.
Rainbow Visualization: This visualization is used in many of our teaser videos: it does automatic foreground/background segmentation and corrects the tracks for the camera motion, so you can visualize the paths objects take through real space.
Standard PyTorch TAPIR: This is the TAPIR / BootsTAPIR model re-implemented in PyTorch, which contains the exact architecture & weights as the Jax model.
Online PyTorch TAPIR: This is the sequential causal BootsTAPIR model re-implemented in PyTorch, which contains the exact architecture & weights as the Jax model.

Live Demo

Clone the repository:

git clone https://github.com/deepmind/tapnet.git

Switch to the project directory:

cd tapnet

Install the tapnet python package (and its requirements for running inference):

pip install .

Download the checkpoint

mkdir checkpoints
wget -P checkpoints https://storage.googleapis.com/dm-tapnet/causal_tapir_checkpoint.npy

Add current path (parent directory of where TapNet is installed) to PYTHONPATH:

export PYTHONPATH=`(cd ../ && pwd)`:`pwd`:$PYTHONPATH

If you want to use CUDA, make sure you install the drivers and a version of JAX that's compatible with your CUDA and CUDNN versions. Refer to the jax manual to install the correct JAX version with CUDA.

You can then run a pretrained causal TAPIR model on a live camera and select points to track:

cd ..
python3 ./tapnet/live_demo.py \

In our tests, we achieved ~17 fps on 480x480 images on a quadro RTX 4000 (a 2018 mobile GPU).

Benchmarks

This repository hosts three separate but related benchmarks: TAP-Vid, its later extension RoboTAP, and TAPVid-3D.

TAP-Vid

tap-vid.mp4

TAP-Vid is a dataset of videos along with point tracks, either manually annotated or obtained from a simulator. The aim is to evaluate tracking of any trackable point on any solid physical surface. Algorithms receive a single query point on some frame, and must produce the rest of the track, i.e., including where that point has moved to (if visible), and whether it is visible, on every other frame. This requires point-level precision (unlike prior work on box and segment tracking) potentially on deformable surfaces (unlike structure from motion) over the long term (unlike optical flow) on potentially any object (i.e. class-agnostic, unlike prior class-specific keypoint tracking on humans).

More details on downloading, using, and evaluating on the TAP-Vid benchmark can be found in the corresponding README.

RoboTAP

RoboTAP is a following work of TAP-Vid and TAPIR that demonstrates point tracking models are important for robotics.

The RoboTAP dataset follows the same annotation format as TAP-Vid, but is released as an addition to TAP-Vid. In terms of domain, RoboTAP dataset is mostly similar to TAP-Vid-RGB-Stacking, with a key difference that all robotics videos are real and manually annotated. Video sources and object categories are also more diversified. The benchmark dataset includes 265 videos, serving for evaluation purpose only. More details can be found in the TAP-Vid README. We also provide a demo of the segmentation algorithm used in the paper.

TAPVid-3D

TAPVid-3D is a dataset and benchmark for evaluating the task of long-range Tracking Any Point in 3D (TAP-3D).

The benchmark features 4,000+ real-world videos, along with their metric 3D position point trajectories. The dataset is contains three different video sources, and spans a variety of object types, motion patterns, and indoor and outdoor environments. This repository folder contains the code to download and generate these annotations and dataset samples to view. Be aware that it has a separate license from TAP-Vid.

More details on downloading, using, and evaluating on the TAPVid-3D benchmark can be found in the corresponding README.

A Note on Coordinates

In our storage datasets, (x, y) coordinates are typically in normalized raster coordinates: i.e., (0, 0) is the upper-left corner of the upper-left pixel, and (1, 1) is the lower-right corner of the lower-right pixel. Our code, however, immediately converts these to regular raster coordinates, matching the output of the Kubric reader: (0, 0) is the upper-left corner of the upper-left pixel, while (h, w) is the lower-right corner of the lower-right pixel, where h is the image height in pixels, and w is the respective width.

When working with 2D coordinates, we typically store them in the order (x, y). However, we typically work with 3D coordinates in the order (t, y, x), where y and x are raster coordinates as above, but t is in frame coordinates, i.e. 0 refers to the first frame, and 0.5 refers to halfway between the first and second frames. Please take care with this: one pixel error can make a difference according to our metrics.

Checkpoints

tapnet/checkpoint/ must contain a file checkpoint.npy that's loadable using our NumpyFileCheckpointer. You can download checkpoints here, which should closely match the ones used in the paper.
