This will open up your webcam as long as it is connected and on. Any errors

is likely due to your webcam being not accessible, or GPU drivers not setup
|
||||
properly.
|
||||
|
||||
## Python
|
||||
|
||||
### Prerequisite
|
||||
|
||||
1. Make sure that Bazel and OpenCV are correctly installed and configured for
|
||||
MediaPipe. Please see [Installation](./install.md) for how to setup Bazel
|
||||
and OpenCV for MediaPipe on Linux and macOS.
|
||||
|
||||
2. Install the following dependencies.
|
||||
|
||||
```bash
|
||||
# Debian or Ubuntu
|
||||
$ sudo apt install python3-dev
|
||||
$ sudo apt install python3-venv
|
||||
$ sudo apt install -y protobuf-compiler
|
||||
```
|
||||
|
||||
```bash
|
||||
# macOS
|
||||
$ brew install protobuf
|
||||
```
|
||||
|
||||
### Set up Python virtual environment.
|
||||
|
||||
1. Activate a Python virtual environment.
|
||||
|
||||
```bash
|
||||
$ python3 -m venv mp_env && source mp_env/bin/activate
|
||||
```
|
||||
|
||||
2. In the virtual environment, go to the MediaPipe repo directory.
|
||||
|
||||
3. Install the required Python packages.
|
||||
|
||||
```bash
|
||||
(mp_env)mediapipe$ pip3 install -r requirements.txt
|
||||
```
|
||||
|
||||
4. Generate and install MediaPipe package.
|
||||
|
||||
```bash
|
||||
(mp_env)mediapipe$ python3 setup.py gen_protos
|
||||
(mp_env)mediapipe$ python3 setup.py install
|
||||
```
|
||||
|
||||
### Run in Python interpreter
|
||||
|
||||
Make sure you are not in the MediaPipe repo directory.
|
||||
|
||||
Using [MediaPipe Pose](../solutions/pose.md) as an example:
|
||||
|
||||
```bash
|
||||
(mp_env)$ python3
|
||||
>>> import mediapipe as mp
|
||||
>>> pose_tracker = mp.examples.UpperBodyPoseTracker()
|
||||
|
||||
# For image input
|
||||
>>> pose_landmarks, _ = pose_tracker.run(input_file='/path/to/input/file', output_file='/path/to/output/file')
|
||||
>>> pose_landmarks, annotated_image = pose_tracker.run(input_file='/path/to/file')
|
||||
|
||||
# For live camera input
|
||||
# (Press Esc within the output image window to stop the run or let it self terminate after 30 seconds.)
|
||||
>>> pose_tracker.run_live()
|
||||
|
||||
# Close the tracker.
|
||||
>>> pose_tracker.close()
|
||||
```
|
||||
|
||||
Tip: Use command `deactivate` to exit the Python virtual environment.

## Overview
|
||||
|
||||
Human pose estimation from video plays a critical role in various applications
|
||||
such as quantifying physical exercises, sign language recognition, and full-body
|
||||
gesture control. For example, it can form the basis for yoga, dance, and fitness
|
||||
applications. It can also enable the overlay of digital content and information
|
||||
on top of the physical world in augmented reality.
|
||||
|
||||
MediaPipe Pose is a ML solution for high-fidelity upper-body pose tracking,
|
||||
inferring 25 2D upper-body landmarks from RGB video frames utilizing our
|
||||
[BlazePose](https://mediapipe.page.link/blazepose-blog) research. Current
|
||||
state-of-the-art approaches rely primarily on powerful desktop environments for
|
||||
inference, whereas our method achieves real-time performance on most modern
|
||||
[mobile phones](#mobile), [desktops/laptops](#desktop), in [python](#python) and
|
||||
even on the [web](#web). A variant of MediaPipe Pose that performs full-body
|
||||
pose tracking on mobile phones will be included in an upcoming release of
|
||||
[ML Kit](https://developers.google.com/ml-kit/early-access/pose-detection).
|
||||
|
||||
 |
|
||||
:--------------------------------------------------------------------------------------------: |
|
||||
*Fig 1. Example of MediaPipe Pose for upper-body pose tracking.* |
|
||||
|
||||
## ML Pipeline
|
||||
|
||||
The solution utilizes a two-step detector-tracker ML pipeline, proven to be
|
||||
effective in our [MediaPipe Hands](./hands.md) and
|
||||
[MediaPipe Face Mesh](./face_mesh.md) solutions. Using a detector, the pipeline
|
||||
first locates the pose region-of-interest (ROI) within the frame. The tracker
|
||||
subsequently predicts the pose landmarks within the ROI using the ROI-cropped
|
||||
frame as input. Note that for video use cases the detector is invoked only as
|
||||
needed, i.e., for the very first frame and when the tracker could no longer
|
||||
identify body pose presence in the previous frame. For other frames the pipeline
|
||||
simply derives the ROI from the previous frame’s pose landmarks.
|
||||
|
||||
The pipeline is implemented as a MediaPipe
|
||||
[graph](https://github.com/google/mediapipe/tree/master/mediapipe/graphs/pose_tracking/upper_body_pose_tracking_gpu.pbtxt)
|
||||
that uses a
|
||||
[pose landmark subgraph](https://github.com/google/mediapipe/tree/master/mediapipe/modules/pose_landmark/pose_landmark_upper_body_gpu.pbtxt)
|
||||
from the
|
||||
[pose landmark module](https://github.com/google/mediapipe/tree/master/mediapipe/modules/pose_landmark)
|
||||
and renders using a dedicated
|
||||
[upper-body pose renderer subgraph](https://github.com/google/mediapipe/tree/master/mediapipe/graphs/pose_tracking/subgraphs/upper_body_pose_renderer_gpu.pbtxt).
|
||||
The
|
||||
[pose landmark subgraph](https://github.com/google/mediapipe/tree/master/mediapipe/modules/pose_landmark/pose_landmark_upper_body_gpu.pbtxt)
|
||||
internally uses a
|
||||
[pose detection subgraph](https://github.com/google/mediapipe/tree/master/mediapipe/modules/pose_detection/pose_detection_gpu.pbtxt)
|
||||
from the
|
||||
[pose detection module](https://github.com/google/mediapipe/tree/master/mediapipe/modules/pose_detection).
|
||||
|
||||
Note: To visualize a graph, copy the graph and paste it into
|
||||
[MediaPipe Visualizer](https://viz.mediapipe.dev/). For more information on how
|
||||
to visualize its associated subgraphs, please see
|
||||
[visualizer documentation](../tools/visualizer.md).
|
||||
|
||||
## Models
|
||||
|
||||
### Pose Detection Model (BlazePose Detector)
|
||||
|
||||
The detector is inspired by our own lightweight
|
||||
[BlazeFace](https://arxiv.org/abs/1907.05047) model, used in
|
||||
[MediaPipe Face Detection](./face_detection.md), as a proxy for a person
|
||||
detector. It explicitly predicts two additional virtual keypoints that firmly
|
||||
describe the human body center, rotation and scale as a circle. Inspired by
|
||||
[Leonardo’s Vitruvian man](https://en.wikipedia.org/wiki/Vitruvian_Man), we
|
||||
predict the midpoint of a person's hips, the radius of a circle circumscribing
|
||||
the whole person, and the incline angle of the line connecting the shoulder and
|
||||
hip midpoints.
|
||||
|
||||
 |
|
||||
:----------------------------------------------------------------------------------------------------: |
|
||||
*Fig 2. Vitruvian man aligned via two virtual keypoints predicted by BlazePose detector in addition to the face bounding box.* |
|
||||
|
||||
### Pose Landmark Model (BlazePose Tracker)
|
||||
|
||||
The landmark model currently included in MediaPipe Pose predicts the location of
|
||||
25 upper-body landmarks (see figure below), with three degrees of freedom each
|
||||
(x, y location and visibility), plus two virtual alignment keypoints. It shares
|
||||
the same architecture as the full-body version that predicts 33 landmarks,
|
||||
described in more detail in the
|
||||
[BlazePose Google AI Blog](https://mediapipe.page.link/blazepose-blog) and in
|
||||
this [paper](https://arxiv.org/abs/2006.10204).

### Python
|
||||
|
||||
Please first see general instructions for
|
||||
[Python](../getting_started/building_examples.md#python) examples.
|
||||
|
||||
```bash
|
||||
(mp_env)$ python3
|
||||
>>> import mediapipe as mp
|
||||
>>> pose_tracker = mp.examples.UpperBodyPoseTracker()
|
||||
|
||||
# For image input
|
||||
>>> pose_landmarks, _ = pose_tracker.run(input_file='/path/to/input/file', output_file='/path/to/output/file')
|
||||
>>> pose_landmarks, annotated_image = pose_tracker.run(input_file='/path/to/file')
|
||||
|
||||
# For live camera input
|
||||
# (Press Esc within the output image window to stop the run or let it self terminate after 30 seconds.)
|
||||
>>> pose_tracker.run_live()
|
||||
|
||||
# Close the tracker.
|
||||
>>> pose_tracker.close()
|
||||
```
