Automated lip-reading: inferring what someone is saying, based upon video of them speaking
Some humans can lip-read fairly well: by watching someone who is speaking, they can tell what the speaker is saying (even without hearing the speech).
Has there been any work on building computer software to lip-read? In other words, given a video…

How does facial recognition work?
I'm interested in learning about how facial recognition works. I'm especially interested in the algorithms or approach that is used. What are the leading methods for facial recognition? Is there a good overview or source to learn about a few of…

Do white box methods for feature extraction exist for facial recognition?
Part of something I'm working on (or rather begin working on) involves white box approaches to facial recognition. I previously worked on something for character recognition using scene segmentation and neural networks but for faces I'm trying to…

How does continuous computer vision works?
First: I have programmed a few programs dealing with computer vision (not with libraries but from scratch):
Simple Character and Figure Recognition
Character and Figure Recognition with Neural networks
Facial recognition
so I am not asking for…

How to detect Farkas or MPEG4 FDP points on image with a face?
Brief problem description
I'm using a Basel Morphable Face Model, which was labeled with MPEG4 and Farkas landmarks. I can generate different faces, use different lighting conditions, rotations, perspective etc.
I want to use it to train an…

How many thresholds and distance matrix are in Eigenface?
I edited my question trying to make it as short and precise.
I am developing a prototype of a facial recognition system for my Graduation Project. I use Eigenface and my main source is the document Turk and Pentland. It is available here:…

Facial Recognition State of the Art Measurement
I would expect issues with the Facial Recognition technology to prompt evaluators to measure performance with metrics such as:
accuracy (e.g. false positives)
poor image quality input handling
speed of algorithm
What are the metrics used to gauge…

Face recognition on on tilted images
From what I learned, viola jones needs images with faces upfront. Tilting the head a few degrees to each side can botch the algorithm. Is it possible to take an image, take a several rotated copies of it and run the algorithm on each one?
This…

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…

Using landmark points on the face for face recognition
I am currently working in area of computer vision for my master's thesis and am trying to use distances between landmark points on the face for recognition.
My question is this: What landmark points should I use for measuring distances between…
