[@scottreigel9911]

thanks. now i have basic AI classifying everything in my immediate area as a face or not via my laptop camera. Love it!!!! 🔥🔥

[@NapoleanBonaparte-bv2hz]

Thanks, G. That was really helpful.

[@bl4z3_kanazaki]

Holy thank you so much my man !! There are a lot of face_detection guides on net and I can't find shit that I understand :3 thanks man

[@scottlee38]

I actually use OpenCV all the time. these are interesting!

[@_ifly]

great tutorial you made it very simple.

[@jarjarbinks8954]

do i need to install opencv in the python installation directory? or just in any location from the command line?

[@flyingzeppo]

Another great and informative video. Thank you. I'm curious if there are still plans for an Intermediate and Advanced C programming playlist. I was really looking forward to those.

[@rashilalan1661]

Thankyou so much for the great vid!

[@jakiez6750]

can we use other trained data for this ?

[@lexal03]

does it record the whole time you are using the facial recognition?

[@mirolimturgunov1455]

Thanks bro for usefull and awasome tutorial

[@suryanshusaxena2082]

Thank you very much sir for this video

[@kingfunny4821]

How can the image be stored in the database? And how to recover the associated data in the recognized image Could you please help me?

[@pydisekhar]

bro tell me what are the interpreuter extensions i need

[@prime2836]

please tell what to do it is constantly saying pip is not recognizes a command in command prompt please help

[@marcolyne7563]

Am facing problems, it is saying" Cannot find reference 'CASCADE_SCALE_IMAGE' in '__init__.py':19"

[@FrogInALog_]

how do I make it so that it makes the square filled

how do we do the same thing but on pictures?

Works on the first try, thank you!

[@arnyoung3209]

@@pydisekhar Write 'gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)' instead. There is capital C in 'cvtColor'

[@pydisekhar]

@Arnyoung thanks dear

[@mattRRgraham1996]

Nice video. I was writing this code in Jupyter Notebook on my 2019 Macbook Pro and when I ran it and had it activate my laptop's camera to capture my face in live time, it worked, but I was wondering how you're supposed to get out of this. When I pressed "q" it freezes. I know q is the key that's supposed to break the loop and make things stop, but the only way I can seem to get out of this and get rid of that faces window is by restarting my kernel which seems inefficient. I was wondering if there was a better way to do this or if I'm just overlooking something simple. Thanks!

[@ravanasura8308]

can you send the code

[@muscababdinaasir2771]

Pro can you send me this code 😢🙏🙏🙏

[@bluebeka2458]

Can you show what packages did you install for this tho? This tutorial is pretty incomplete also feels more like a speedrun than a tutorial.

[@__money__mindset_..848]

can somebody help i got this error:opencv-python\opencv\modules\core\src\persistence.cpp (505) cv::FileStorage::Impl::open Can't open file: 'D:\pythonProject1\venv\lib\site-packages\cv2\data\haarcascade_forntalface_default.xml' in read mode

I keep getting error:OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor' For some reason my IDE is not lining the line gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

[@Omer.Ravid1]

me too, you know how to solve it?

[@jacobsucks4124]

i changed "COLOR_BGR2GRAY" to "COLOR_RGBA2GRAY" and it started working

[@jakesnell7707]

Can you do a video series on using git?

[@BOHICAMAN1]

Wrote your code exactly. Ran it for my camera video and it found my face. When I changed video feed to a properly installed video (mp4), I get error: "gray = cv2.cvtColor(frame, cv2.COLOR_GRAY)". Then it says: cv2.error: OpenCV(4.10.0) D:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\color.cpp:196: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'. Anyone have an idea what is wrong??

Someone help me, How do I install that harr file (the pretrained model)

Great Video! But I am not able to install Opencv:

[@g.s.3389]

suggestion: cvlib works better, why don't you make a video on it. :)
