# Hand Landmark from Google Mediapipe validated for Unity Sentis
This is the [Hand Landmark model](https://developers.google.com/mediapipe/solutions/vision/hand_landmarker) from Google in the Sentis format.

The model detects 3D markers on a hand centered in an image. You could use these markers, for example, to control a bone rig.

**IMPORTANT:** The hands needs to be centered and cropped to fit the image. For images with hands not in the center or for multiple hands, you will need another model to detect hands, and crop them before feeding them into this model. For example you could use [Blaze Palm](https://huggingface.co/unity/sentis-blaze-palm) to detect them (but this model only works with open palms).

## How to Use
* Create a new scene in Unity 2023
* Install `com.unity.sentis` version `1.3.0-pre.3` from the package manager
* Put the hand_landmark.sentis file in the `Assets/StreamingAssets` folder
* Put a video in the `Assets/StreamingAssets` folder and set `videoName` variable to the video name
* Create a RawImage and place it in your scene. Link to this image in the `previewUI` field.
