<p>Basically, you will need a <a href="https://arxiv.org/abs/1503.03832" rel="nofollow noreferrer">FaceNet</a> pretrained model. A FaceNet model creates an embedding vector for a human face in an image. As mentioned in the paper, researchers have used clustering algorithms using the embedded face vectors. Hence, you get a 128 or 256-dimensional vector which represents that human face.</p>

<ul>
<li>After you've generated an embedding vector from the images of the two subjects, you can find the <a href="https://en.wikipedia.org/wiki/Cosine_similarity" rel="nofollow noreferrer">cosine similarity</a> of both the vectors, which is a common metric used for vectors comparison.</li>
<li>By some experimenting, you can find some <strong>threshold similarity score</strong>, meaning, if the similarity scores exceed this threshold score, the faces are of the same subjects.</li>
</ul>

Looking for recommendations on how to approch a face verification system and trying to find pre-trained models
<p>I have failed miserably trying to train a face verification network on my own hardware. Here by face verification i mean looking at two photos and telling its the same person or not. So any recommendations for pre trained models?</p>

<p>there are many articles on implementation of face-net for face identification but none for face verification. Can anyone guide me if you know of any pre trained models that i can use?</p>
