Awesome tutorial! Your explanations are just as much detailed as it is necessary for a beginner to get interested and learn quite a lot as well.

i really appreciate this tutorial, thanks you!

Thank you very much for this video. Would you have any hints/resources to provide for doing the same but for overlaying videos instead of images on the video?

Great tutorial. Worked perfectly. How would i go about making the overlay opaque instead of being transparent? I tried setting alpha value to 1.0 in the setWeighted method for the overlay image but the overlay still looks transparent if the camera feed in the background has light colors. If the camera feed is dark or black then the overlay icon appears opaque as required. How do i make it opaque irrespective of the background camera feed? Thanks and looking forward to your reply.

very interesting overlay information. What would be a good opencv method to overlay a spreadsheet over a webcam video and edit the spreadsheet on a touchscreen live? Some cameras have this feature for setup, etc. thanks.

Hello, how are you
I have read your activities in Python and I hope you will help me. I have a research on the use of the (BRISK) detector using the Python language., can you help me please

Hi, thank you for the video it's great!!!
but I am wondering what I should do if I want the overlay image(watermark here) to be always on top of every bounding boxes of the objects it detected ??
Would be fantastic if you would enlighten me!!!

[drmurray]

could you add the watermark to the overlay before the while, and just addweight the overlay to the frame in the while loop

thanks sir, also sir please tell can we remove overlay floating watermark from any video through opencv and if yes, then please

[hakansenturk]

Hey Great Job man, thank you a lot! one question how can I add a text watermark to my video without importing any picture but just by writing what I want to show?

Your video is extremely helpful, thank you for the awesome video. I learned a lot from this. 
But I'm wondering when have I have some x, y position received from the webcam, how can I implement it?
I tried putting x and y into this form: h_offset = x - img_h - offset, w_offset = y - img_w 
with overlay[i + h_offset, j + w_offset] = img[i, j]
but the compiler gives this error: IndexError: index 720 is out of bounds for axis 0 with size 720 :(((

Great video but I'm getting errors about frame.shape that I havn't found an answer to.

where can I find the code source please
