Multiple Face Extraction

The Multiple Face Extraction API detects and extracts all individual faces present in a single image. It is designed for group photos or any image with more than one person, returning a cropped face image and confidence score for each detected face.

How It Works

Submit a Base64-encoded image containing one or more faces. The API detects all faces in the image and returns each extracted face as a separate Base64 image, along with a confidence score indicating detection certainty.

Request Parameters

Image Guidelines

• Supported formats: JPG, PNG.
• The image can contain multiple faces.
• Ensure faces are clearly visible and not heavily occluded.
• Maximum image size: 8 MB.
• Higher resolution images improve detection accuracy.

Response

On success, returns a data array where each item contains:

• confidence — detection confidence score (e.g., "0.9998"). Higher is better.
• image — Base64-encoded cropped face image for that individual.
