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 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…

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…

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…

How to tackle the human error made in labeling datasets for classification tasks like facial expression recognition?

I am working on the Facial Expression Recognition Task. One of the most challenging tasks that I faced was human error in labeling the datasets (ex: let's say FER2013). Are there anyways to Handle incorrect labeling of datasets in the classification…

What is the minimum video resolution I need to identify anyone with facial recognition?

I am currently working on a small project where I am trying to automate some stuff at home. I am building a model capable of identifying my face with OpenCV. This will be a live feed. I am making the project's estimations and have a really low…

Is there any published research on the information-carrying capacity of the human face?

Is there any published research on the information-carrying capacity of the human face? Here I mean "how much information can be conveyed via facial expressions & micro-expressions". This is a subject of interest because the human face is…
