You are such a saviour, thank you so much man. I wanted this so bad

[NiVofHiR]

Great video tutorial, thanks for sharing!

[halilavc]

Thanks bro . Amazing . Thank you so much

[cybercribe]

Nice tutorial but a doubt how did you detect the values of lower_red, blue, green and upper_red, blue, green??

[mauriziovetere]

Nice tutorial! Is there a way to detect all chosen colors on one screen sweep instead of repeating the operation for each of them? I'm talking about the inRange() and bitwise_and() parts, I ask for performance purposes

[NeilSummersgill]

cv2.createTrackbar for HSV is very useful for getting the ranges correct

Thank you for this video, have you an idea how i can detect white cracks in a white surface, but the saturation of the surface and cracks are not similar.
thanks

hi sergio, can i ask something, if i wanna actuate a servo motor, after the camera detected one particular color, what function should i use ?

[rajvindermann]

Hi, may i know how to detect the object which has similar colour to the background? Thank you.

[aliihsancukur]

can you do applications with some more advanced functions ? for example imutils related to thank you

[johntran]

Hi, what if I only want to detect only the white color, can you tell me what is the threshold or someway to calculate it? Thank you

[lokeshsaha]

Hey, can you please help me how to detect background color of an image?

[abdelrhmanshokr]

great video thanks a lot but I've an issue here no matter what ranges of colours I pass as high and low I keep getting a black image as a result and I don't really get why can anyone help me understand why this is happening (I am trying to block all colours except for black) but again I wrote the same code with the same values to make sure that the problem isn't with my ranges but the same result always pops up a black image with rgb = 0, 0, 0 and as I said I don't get it

[francescopistone]

Does somebody know how to make that in C++(Visual Studio)?

[coursfiliereeln]

hello thank you for the video it's helpful.. i have a question? if we need to apply this with depth images how i can do this?

[raghuld]

I'm doing a similar project with OpenCV. Could you help me with that, sir????

[kevinliem]

hi bro nice tutorial, i want to ask something, how if we want to add more color on it? lets say we want to add secondary color, like purple, maroon or something else? how is it?

[ankor]

If Color is detected the it show message like image is detected...How i print that message

[ramadhaniramadhani]

Hello sir, why i can't run cV2.bitwise_and on my PC. Can you explain about it?

[brunorafaelalmeida]

Thanks for the video concepts, but here for me the jupyter notebook (where I use to develop these types of programs) gives an error after I finish the program, and to get around this it is good practice to destroy the images and data that will not be most used after the end of the program. After doing this, the error in my kernel stopped showing up. This destruction of data that will not be used after the end of the program can be done by the following lines at the end of the program and outside the loop and conditional:
cap.release()
cv2.destroyAllWindows()
PS: Hope this is helpful to someone.
