Man. 4 years ago when I was teenager I met processing and openCV for the first time and I get crazy because it was SUPER cool to make art and crazy stuffs with it but it was too hard and don't know anything about programming. Now you gave me this tutorial (I'm kind late for this video actually) but I should thank you so much because (now I know python) you make everything much easier to understand and get me into it again. Thank you so much. My next object is to make machine learning with some graphical interfaces to see how and what computer doing in the process of learning just for like a game. If you have some tips (not tutorial, I want to learn it by my own) I appreciate.

@balthiertsk8596 2 года назад

Hey Justin, this is an amazing tutorial, thanks! I do want to share that the "conf" of CV2's predict are actually losses. So the higher it is, the more uncertain the prediction is!

@Leonscott80 2 года назад

Wow, this has to be the most useful tutorial I've followed, not only did you make it work accordingly, you explained concisely what each part of the code does step by step, without assuming that whoever was watching already knew what it does, thank you for making this! And as a side note, I really can't blame the classifier for recognizing you as Nikolaj! Face Classifier: "Bro, it's the same guy!"

@Dip_Physics 4 года назад

Awesome tutorial. What helped me most is your line by line explanation of the code that you wrote. Thank you a ton teacher.

@CubedAgency 2 года назад

Thanks for the great content and lessons! BTW, it's recorded in BGR and not (RGB) because when the developers originally made OpenCV, webcams and other cameras used the BGR method as the standard color definitions. That made the conversion process from numerical values for HEX much easier.

@arnavsingh4241 2 года назад

@emilbarothi7834 3 года назад

First of all thank you for the great tutorial. I've rarely encountered such a great introduction. From what I can figure out, one potential cause for the poor quality of identifying the right person is the fact that faces will not be detected in all the photos. At least in my instance, no face is recognized in the pictures with Peter Dinklage whereas for Kit Harington 5 / 6 pictures were recognized as having faces in them. So yeah, there is still some room for improvement and experimenting around. Great video!

@clintonomondi4949 4 года назад

I think the fastest way to get image data for maybe members of your family is asking the to stand in front of the webcam and using opencv take the region of interest per frame and saving them... this would generate hundreds of images and in a short time... For CNNs,the more the data the better....

@jonmayer 5 лет назад

Great video. You make it look very easy to get this started. One suggestion: Maybe print out the confidence number so you can see if it's just too low of a threshold. It might not really think you are anyone from the training, but you're closer to the other people. I would imagine trusting this at a 75% confidence should be realistically attainable.
