## MediaPipe in Python
|
||||
|
||||
MediaPipe offers customizable Python solutions as a prebuilt Python package on
|
||||
[PyPI](https://pypi.org/project/mediapipe/), which can be installed simply with
|
||||
`pip install mediapipe`. It also provides tools for users to build their own
|
||||
solutions. Please see
|
||||
[MediaPipe in Python](https://google.github.io/mediapipe/getting_started/python)
|
||||
for more info.
|
||||
|
||||
## MediaPipe on the Web
|
||||
|
||||
MediaPipe on the Web is an effort to run the same ML solutions built for mobile
|
||||
and desktop also in web browsers. The official API is under construction, but
|
||||
the core technology has been proven effective. Please see
|
||||
[MediaPipe on the Web](https://developers.googleblog.com/2020/01/mediapipe-on-web.html)
|
||||
in Google Developers Blog for details.
|
||||
|
||||
You can use the following links to load a demo in the MediaPipe Visualizer, and
|
||||
over there click the "Runner" icon in the top bar like shown below. The demos
|
||||
use your webcam video as input, which is processed all locally in real-time and
|
||||
never leaves your device.

sparse model is ~30% faster when executing on CPU via

* `z`: Represents the landmark depth with the depth at the midpoint of hips

being the origin, and the smaller the value the closer the landmark is to
|

the camera. The magnitude of `z` uses roughly the same scale as `x`.
|

* `visibility`: A value in `[0.0, 1.0]` indicating the likelihood of the

landmark being visible (present and not occluded) in the image.
