Real-Time Facial Recognition
This plugin allows you to capture faces using the device's camera and compare them with a list of predefined images, identifying matches based on facial similarity. Ideal for authentication, access control, time and attendance, identity validation, and other modern applications with visual recognition.

Features:

🎥 Live capture via webcam.
📁 Comparison with multiple images provided via URL.
✅ Automatic face detection.
🔍 Similarity calculation with precision (threshold) adjustment.
🚦 Exposed States: Face detected, match found, corresponding image, match distance, and error messages.
⚡ Custom events: Face detected, match found.
🛑 Action to stop recognition at any time.


You can use it to log in, grant access, and more.


The plugin basically returns:

1) Results of comparisons between the person on the camera and a list of images you uploaded.

2) If a face (any) is identified on the camera.

3) *NEW* : The Facial Expression, age and gender of the person on the camera.

4) *NEW* : if the 'Show square around face?' option is enabled, it will draw a square around the face of the person detected on the camera. You can dynamically choose the color of this square.

5) *NEW* : Now you have a new action: take a photo of the person on camera. When this action is triggered, take a screenshot of the camera, saving it in the Cam Picture state. You can use it, for example, in a conditional statement: every time the expression is 'happy,' take a screenshot of the image and save it to your database, or something similar.

Now you have a new action: take a photo of the person on the camera. When this action is triggered, take a screenshot from the camera, saving it in the Cam Picture state. You can use it, for example, in a conditional: every time the expression is 'happy,' take a screenshot of the image and save it to your database, or something similar. Now you have the "an_image_was_captured_from_the_camera" event, which, whenever an image is available in the Cam Picture state, you can trigger this event.
