# MediaPipe OSC
[MediaPipe](https://google.github.io/mediapipe/) examples which stream their detections over OSC to be used in other applications.
### Install & Run
Currently this is only tested on Windows and MacOS. It's recommended to use Python3 (`>3.7`) and a virtual environment.
```bash
python install -r requirements.txt
```
To run an example use the basic python command to start up the script.
```bash
# start pose detection with webcam 0
python pose.py --input 0
# start pose detection with video
python pose.py --input yoga.mp4
```
Other parameters are documented in the following list or algorithm specific.
- **input** - The video input path or video camera id (default `0`)
- **min-detection-confidence** - Minimum confidence value ([0.0, 1.0]) for the detection to be considered successful. (default `0.5`)
- **min-tracking-confidence** - Minimum confidence value ([0.0, 1.0]) to be considered tracked successfully. (default `0.5`)
- **ip** - OSC ip address to send to (default `127.0.0.1`)
- **port** - OSC port to send to (default `7500`)
### Full-Body Pose Landmark Model (BlazePose Tracker)
The landmark model currently included in MediaPipe Pose predicts the location of 33 full-body landmarks (see figure below), each with (`x, y, z, visibility`). Note that the z value should be discarded as the model is currently not fully trained to predict depth, but this is something we have on the roadmap.
*[Reference: mediapipe/solutions/pose](https://google.github.io/mediapipe/solutions/pose#pose-landmark-model-blazepose-tracker)*
**Additional Parameters**
```
--model-complexity MODEL_COMPLEXITY
Set model complexity (0=Light, 1=Full, 2=Heavy).
--no-smooth-landmarks
Disable landmark smoothing.
--static-image-mode Enables static image mode.
```
#### Format
- `count` - Indicates how many poses are detected (currently only `0` or `1`)
- list of landmarks (`33` per pose) (if pose has been detected)
- `x` - X-Position of the landmark
- `y` - Y-Position of the landmark
- `z` - Z-Position of the landmark
- `visibility` - Visibility of the landmark
```
/mediapipe/pose [count, x, y, z, visibility, x, y, z, visibility ...]
```
### Hand Detection
The [hand detection model](https://google.github.io/mediapipe/solutions/hands.html) is able to detect and track 21 3D landmarks.
#### Format
- `count` - Indicates how many hands are detected
- list of landmarks (`21` per hand) (if hands has been detected)
- `x` - X-Position of the landmark
- `y` - Y-Position of the landmark
- `z` - Z-Position of the landmark
- `visibility` - Visibility of the landmark
```
/mediapipe/hands [count, x, y, z, visibility, x, y, z, visibility ...]
```
### Face Detection
The [face detection model](https://google.github.io/mediapipe/solutions/face_detection.html) is able to detect multiple faces and 5 keypoints. At the moment only the bounding box is sent over OSC.
#### Format
All values are normalized to the image width and height.
- `count` - Indicates how many faces are detected
- list of one bounding box per face (if faces has been detected)
- `xmin` - X-Position of the top-left bounding box anchor
- `ymin` - Y-Position of the top-left bounding box anchor
- `width` - Width of the bounding box
- `height` - Height of the bounding box
- `score` - Confidence score of the bounding box
```
/mediapipe/faces [count, xmin, ymin, width, height, score, xmin, ymin, width, height, score ...]
```
