Extending FaceNet’s triplet loss to object recognition

FaceNet uses a novel loss metric (triplet loss) to train a model to output embeddings (128-D from the paper), such that any two faces of the same identity will have a small Euclidean distance, and such that any two faces of different identities will…

Is algorithmic bias due to the training dataset used?

I recently read about algorithmic bias in facial recognition. Is algorithmic bias due to the training dataset used, or is it due to something else?

Is it possible to fool a facial recognition algorithm?

Assuming we're dealing with an artificial neural network (e.g. a ConvNet), which was trained by a large dataset of human faces. Are there any known issues or challenges where facial recognition would fail? I'm not talking about covering half of the…

Viola Jones Algorithm

Can Viola Jones algorithm be used to detect the facial emotion. Actually it was used in creating harr-cascade file for object and facial detection, but what confused me is whether it can be used to train for emotion detection. If not, what…

How to identify the face of a certain customer in a grocery store?

How would you solve the problem of identifying certain customer in a grocery store? Suppose our client is already signed-up on our website with an unique ID given to him. To come in to the store, firstly he must place a phone with a QR code in front…

Why are the landmark retrieval and facial recognition literature so divergent?

Context and detail I've been working on a particular image retrieval problem and I've found two popular threads in the literature: Image retrieval (usually benchmarked with landmark retrieval datasets) [x] Neural codes for Image Retrieval [x]…

Facial recognition and classifying unknowns with neural networks

As far as I understand, neural networks aren't good at classifying 'unknowns', i.e. objects that do not belong to a learned class. But how do face detection/recognition approaches usually determine that no face is detected/recognised in a region? Is…

Is it possible to do face recognition with just the eyes?

Assuming the input photo is focused on a person's face, if the person is wearing a surgical mask, most face recognition software fail to identify the subject's face. Most facial landmark models are trained to identify at least the eyes and the tip…

How to identify if 2 faces contain the same person?

I have got numerous frames and I've detected all the faces in all the frames using Retinaface. However I need to track the faces of people over frames. For this purpose, I assumed I could try finding the landmarks from the face using libraries like…

Does anyone know of a model for comparing the eyes of people in two images to see if they match?

There’s a lot of talk of undercover cops intentionally starting violence in otherwise peaceful protests. The evidence, primarily, are images like this. https://images.app.goo.gl/4n3o2EXwFzMQfsKq6 It looks pretty convincing, but I’d like something…

How to implement fisherface algorithm and how much time will it take?

I found on the web that fisherface is the best algorithm for face detection. Before investing deeply into it, I just want to know how hard is it to implement it and how much time will it take. I am new to this website and I welcome any suggestions.

Machine learning approach to facial recognition

First of all I'm very new to the field. Maybe my question is a bit too naive or even trivial... I'm currently trying to understand how can I go about recognizing different faces. Here is what I tried so far and the main issues with each approach: 1)…

Can I recognize the faces of people around the world?

I created a system where every moment takes photos of the face of who is in the vision of the camera. Initially I took 500 photos of me, to recognize its creator. This takes approximately 20 seconds. Then every moment he recognizes faces and if it…
