A most interesting OpenCV video. I have a new Orange Pi-5 SBC and would like to do some OpenCV Python examples on it. The Raspberry Pi-4 has a wealth of examples to practice with first. This wonderful Tutorial Shape Detection lesson [9] will be very helpful. 😎 Thank you.
Can you give me the link for this course, the link in description just redirects me to the new website of yours. I cant find this particular project there. Thanks
I am little confuse here? Is it calculating are of the bounding box around the object or area of the object itself? I think it's calculating of bounding box? Btw the tutorial is good ❤️💯
Anyone knows how to find out the coordinates of the shapes detected? Any help would be really appreciated. Also the tutorial's really really helpful. Thanks!

@@jericreyechavez9 You can follow this tutorial ( th-cam.com/video/dZ4itBvIjVY/w-d-xo.html ) with the full body cascade which should give you a bounding box around a human body. Then u could used a fixed coefficient for pixel to cm to find the height. Your camera and target position should be fixed though.
it seems a matter of how you aproximate the contour, and the shape you draw around it. Maybe there's a function to measure the angles between the segments, and maybe you can compare the are and the perimeter, to see if they are compatible with a circle.

you can use the face dlib to get the contours. If you want to use this method in the video, then its better to first detect the face and eye using the haarcascade method. (here is the tutorial).

I want to draw contour around my eye pupil only how to do it
you can use the face dlib to get the contours. If you want to use this method in the video, then its better to first detect the face and eye using the haarcascade method. (here is the tutorial).
