Advanced Computer Vision with Python - Full Course

Anyone else run into the divided by zero error when making the face detection module? The error comes from line 11 where fps = 1/cTime -pTime . cTime is set as time.time() while pTime is set to cTime which means they are the same value resulting in 0 being their difference. This error seemingly prevents the script from executing though, sometimes it just runs until it runs into the error. Any notes to fix this?

how do I open the "hands" in parameters if I'm on a mac, he said to control right click but it doesn't work.

how could I get the codes through websites

some link error? can u share trainer ai videos and jpg for demos?

NC

Amazing

i have problem in transforming the poseEstimationmin to pose module what to do help guys

AttributeError: module 'cv2.dnn' has no attribute 'DictValue'
I got some error, please help me fix this error.

quick hint if your video is too big for the screen:

cv2.namedWindow("Resized_Window", cv2.WINDOW_NORMAL)
cv2.resizeWindow("Resized_Window", 1200, 700)

cv2.imshow("Resized_Window", img)

### resized window values are the rectangle sides, you can adjust them as you wish

In Pose Estimation, how can i find the z cordinate ? and show the depth frame also with poses?

casualy uploads a 6 hour comp vision course brooo, thanks bhai !

Can I use vs code instead? If yes, how do i integrate mediapipe & opencv like he did?

Great course!

Imgae = I am gay

Replace FACE_CONNECTIONS with FACEMESH_TESSELATION if you get an attribute error (Face Mesh section)

Hand Tracking module does not work..

Can I use vs code for my learning instead of pycharm as used in this tutorial?

I finally finished. what an adventure it was! Thank you to everyone who contributed 🙏

Why i can not install mediapipe . Its give an error

Great video, congratulations!! Can mediapipe be adapted to recognize the foot palm (like the hand) ?

help. What should I do if the automatically translated subtitles are not displayed in the second half of the video?

I couldn't down load OpenCV in current platform.

How do you fix the point out of bounds error?

cant we detect multiple pose?

Would we able to import this python script in blender for object tracking??

hii sir ,i want to install a library named mediapipe for my project and i have 3.11 version of the python and im facing problem in installing the library ,will you please help me out for doing this plz plz plz

Okay I tried 10 hours but unable to install mediapipe , now some one has to help me please

can you do pose estimation with pictures rather than video?

where to get the videos of pose detection

Sir I am unable to access the source code you provided through the link you have given in description

Is this for beginners??

Hey guys if u are getting any errors in hand tracking module please refer to the below code:---

i'm only 40 minutes in the course and WOW!
thank you very much!

post code in comments

This is such a great course, my man just gave everyone the steps to a free working AI framework. That you can customize if you put your own time in. You sir deserve the recognition o7.

What are prerequisites for this video can any one please tell me? If you know

why do we get an error when we open the link to the code?

Could you please gave me the code

How can I download images for finger counter project ?

For me, I install python 3.8.10 version again and uninstall my new version. It fix the error installing mediapipe. It helps you to keep going this courses. I don't know why python 3.11 doesn't work.

ikd why I cant run the module properly even I extractly like yours, but when I import this module in another file then it still work well, its kinda confused for me

If someone is having issues like "cannot find videocapture in ___in....bla bla"
Right click on Lib folder and mark directory as source

Hi, i´m beginer in programation, bot your tutorial is very comprensive , thanks
