P.S: If you want to get contours of each separate object, then you can use another image where objects are separated.

What a great Tutorial! Helped me a lot to finish a quick test that i needed, never used neither these technologies! Was just a bit confused at whick platform you've used, but i could figure it out! Ty!

Good tutorial man! This is easy to follow and nice for beginners!

[ultraplayer]

wow thanks so much, I tried many tutorials for doing this and yours explained it the best.

Thanks for the tutorial. It is helpful. But I lost my sense of balance at the 11x11 blur kernel 😂

Hi, Thank you! How to count the number of coins when its arranged like a stack(Vertically)?

[ijazahamed]

shortly well explained. If you can put the combined code it will be more easier to copy and paste.lol

Can it read a tray full of pencils (white color pencil but contour is visible (roughly as the color is white), 4000+ pencils)?

[igordebastiani]

Hello! Nice video, the code is very well written.

[__Abu_Ali__]

how can you find the coordinate of the center for each coin, and print the results as (x, y) table????

Edit: (4hrs later), I found the solution:

for i in cnt:
M = cv2.moments(i)
if M['m00'] != 0:
cx = int(M['m10']/M['m00'])
cy = int(M['m01']/M['m00'])
print(f"x: {cx} y: {cy}")

Thank me later!

hi, can i use this method to count irregular shapes? such as drone image of forest trees?

[ashokkumarbhishma]

Sir,
I am getting "too many values to unpack error" in the line 18. that (cnt, heirarchy line )
please help me to resolve this

Hi, thank you, great video. Could you please explain what the last 3 lines do?(apart from the print statement). I commented them out and the code still worked, counting 24 coins. Thanks again
