Face Verification using MLKIT Vision

To verify if two faces are identical using ML Kit Vision:

1. Capture the user's face using ML Kit Vision for face detection.
2. Compare the captured face with the stored face using face recognition techniques or similarity metrics like cosine similarity.
3. If the similarity score exceeds a certain threshold, consider the faces as identical.

Please note that ML Kit Vision primarily focuses on face detection, not face recognition. For face recognition, you might need to use a dedicated face recognition library or implement a deep learning model.

you can do it like this 

// Step 1: Store contour
val storedcontours: List = // List of face contour stored in internal storage

// Step 2: Capture User Face
val capturedImage: Bitmap = // Captured user's face image
val capturedFacecontour: FloatArray = // Compute contour for the captured face using ML Kit

// Step 3: Compare contour
for (storedcontour in storedcontours) {
    val similarityScore = calculateSimilarityScore(capturedFacecontour, storedcontour)
    if (similarityScore > threshold) {
        // Face match found, user is verified
        break
    }
}
