Facial recognition

Hi everyone,
any of you have any suggestions for implementing facial recognition in an application?
Thank you

Hi Danilo

Depends what you mean by "implementing" ?

If you mean programming it, then my somewhat negative advice is DO NOT even try.

It would be a mass of mathematics. Projections, Matrix manipulations and so on. XSharp would not be the best language to use.

Maybe there is some library somewhere that could be referenced. However facial recognition is being widely researched and at great cost.

If you did find one my guess is that it would be expensive.

I'm wondering why you would need this in what I assume is a Business App. Falls more into the security domain I would have thought.

Best Regards

Terry

Hi Danilo,
Microsoft or Google should have some webservices for this.
I don't think you will be able to find locally installable libraries - and if you may find them, they may be at an unaffordable cost.

for over 10 years I have been developing web applications for attendance and access control.
The idea would be to replace the classic badge with qrcode with facial recognition for visitors to a company.
So when a visitor enters a company for the first time, he registers by memorizing her face. The following times it would be sufficient to show the face to enter.

Hi Danilo,
IMHO this is mainly a GDPR question - such data are highly sensible and I have my doubts that visitors will permit the use of their biometric data.
And using cloud services outside the EU will be even harder.
Before investing time into this research, you should speak to a GDPR experienced lawyer.

Here I had found this, but there is not much documentation ...

Hi Danilo,

some years ago I did some experiments with OpenCV for license plate recognition. IIRC this library was also intended for facial recognition (beside several other image processing options). But I have cancelled the project due to affordable cameras with integrated license plate recognition.

Hello Danilo,

Maybe you can buy a library on Ali Express

Whole China is stuffed with camera's with facial recognition.

Hi...

there is an Azure Cognitive Service called Face Api.

https://azure.microsoft.com/en-us/servi ... ices/face/

There is a Free Tier available, that offers 20 Transactions/Minute and 30.000 Transaction/Month.

Using a hosted service for this is IMHO a good idea, because the service provider is responsible for security and privacy.
