Can an AI generated image (such as pic of human face) be detected that it's AI generated?
AIs are getting better and better at creating images and art. Some of the stuff is almost impossible to be detected by the naked eye. But what about programs and algorithms? Instead of creating an image, can anything detect that this image was…

Can a face recognition system be trained using only computer generated hyper realistic faces?
In order to train a face recognition system you need to have access to a large database with thousands of photos containing different faces. Companies like facebook and amazon have these databases but most average people do not.
If you don't have…

Do different camera angles affect the performance of the deep learning model?
I'm working on a project to build a face recognition system and I have a question: do different camera angles affect the performance of the deep learning model?
For example, in CCTV, training data and testing data are taken using different camera…

Is it feasible to perform facial recognition on hundreds of thousands of individuals?
I came across a video with the title "you can buy things with your face in China". in the video, a woman scanned her face into a vending machine to buy a drink with only her face and without anything else. The description claimed that each face is a…

Does the converted (now square) distorted image of a face affect the accuracy of the calculation of the similarity in FaceNet?
As far as I know,
FaceNet requires a square image as an input.
MTCNN can detect and crop the original image as a square, but distortion occurs.
Is it okay to feed the converted (now square) distorted image into FaceNet? Does it affect the…

Face detection and replacement in photos
I have 2 photos, and my goal is to detect the face in one and place it on the face of the person in the other photo- basically face detection and replacement. It's not deep fakes. It's more of a computer vision-based approach for smoothing the edges…

What is a "center loss"?
I have seen that a center loss is beneficial in computer vision, especially in face recognition. I have tried to understand this concept from the following material
A Discriminative Feature Learning Approach for Deep Face…

Translation in AAM(Active Apperance Model) causing issue
When i apply translation on the landmark, it make the points move to top left, Moreover, when applied with scale it make it compact
I know what the translation do but moving to top left feels like an issue to me,... Or is this suppose to be…

Find all face-recognition matches in JPEG files, which are similar to a corpus of n example photos
This code works, with keras_facenet, to find all files in photos/*.jpg matching the face present in me.jpg:
import glob, os, cv2
from keras_facenet import FaceNet
embedder = FaceNet()
detections = embedder.extract("me.jpg", threshold=0.95)
me_emb =…

Is it possible to build a facial recognition system using a multi-layered DNN?
I am completely new to AI. As the title says, is it possible to build a facial recognition system using a multi-layered DNN? Would this be effective/practical?
I want to implement such a neural network in Python, without the use of any external…

What is the difference between face identification, face verification, and face recognition?
I am confused. On some websites, face identification is just face detection, while face verification is finding the person's identification. They are both considered components of face recognition. But in some websites face verification is 1-to-1…

Arcface implementation for image similarity produces opposite embeddings for positive negative image pairs
So I've built an arcface model with this arcface layer implementation:
https://github.com/4uiiurz1/keras-arcface/blob/master/metrics.py
I trained for a few epochs and now that I'm comparing the results I'm quite baffled.
According to the paper and…

In a face database containing multiple images per subject, how do we determine the face image which is most suited for face recognition?
Let us imagine a face database with several subjects, each subject having multiple face images. How do we determine which is the best face suitable for face recognition purposes?
