With face recognition, we not only identify the person by drawing a box on his face but we also know how to give a precise name. With OpenCV and Python, through a database, we compare the person's photo and we know how to identify it precisely. For example in the preview photo, the software was able to tell that person in the photo is Jeff Bezos.

This is amazing and it works (python 3.7, pip installs), thank you!

@selenawilliams5051 Год назад

This is great, thank you for sharing! I am working on a research project related to real-time facial expression recognition for mental health. Could you post a video that implements facial expression recognition on top of this?

@fadhelalsuwaidi1221 2 года назад

could u work in multiple dataset for on person for make the detection more accurate, this would be great.

@leilaghasemzade5880 2 года назад

Thanks for the tut. How this library recognize the people? when you show a different pics of the same people how it can understand that this is that person? by what technique it compares photos?

@omidalekasir4736 Год назад

Awesome! The question is, why is it working so smoothly? Causey I wrote the same thing with face_recognition and it only shows 1 frame per second. Is your CPU like really powerful? I tried to run it on GPU but it didn't work!

@henkhbit5748 2 года назад

Indeed a great library for image recognition. But I found that when a person face is slanted in the picture, say 30 degrees then the face_encodings function will get an exception. That is a drawback of this module..., otherwise it does an exellent job for face matching.

@vamshimaskuri5208 Год назад

Yes

@pysource is there any way to write by eye using virtual keyboard on the screen without using blinking?

@pysource-com 2 года назад

It would be possible by having some hat keeping the webcam a few centimeters from the eye, because otherwise with the eye too far, it won't be precise enough and it would be almost impossible to hit the keys correctly

@hakunamatata1035 9 месяцев назад

Is this also able to detect side faces

@cgoody3170 Год назад

Ive noticed a lot of comments here by folks wanting to scale up the recognition to many thousands of images. There are solutions to this but you will need to learn about high performance computing architectures first and that is a field in of itself. But to be honest: if you don't know how to scale this problem then you should question whether you should be even trying, since the legal and ethical issues you may encounter if you get it wrong may land you in serious trouble. Great tutorial though.

Now we use a while loop to load the frames from the camera. The concept is the same, simply instead of getting the frames from the camera on the while loop, you loop through the images of a folder

There should be more accuracy, and for future do one thing that store encodings in a excel file so that one can have his face encodings and that will help to make face decoders in future.

I agree about the accuracy. I on purpose (reduced the accuracy on this one, by shrinking image size that is processed) to make it in realtime with just the CPU.

@serkankaracan9014 2 года назад

I changed the project a bit. My aim is to open the door by opening the magnetic lock when the camera sees my face. There is a button in my project. When I press the button, the cv2 library is activated. At this time, when the camera sees my face, I activate the relay for 3 seconds, then the relay turns off. But this relay pull event happens many times. I guess it's a problem like this because it frames my face so many times. What kind of arrangement do I need to take only 1 frame and turn the relay on and off. Thanks for your help..

@Gh0st_0723 2 года назад

Instead of capturing the camera live, have it capture the first or second frame only eg cv2.frame ...
