Detecting colors (Hsv Color Space) - Opencv with Python

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?

Bravoooooooooooooooooo

Hi Sergio! Can you tell us what that cool software for picking colors is called? I really need it. Thanks

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

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

Hi Pysource, if the background color is similar to the object color, is there a way to detect and draw only the outline of the object?

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.

It shows can't find camera device..could someone help me...

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

Hi nice video for leaning for color deduction. I want to know what is the logic to find color lower and upper hsv value without any tool. Can you share the easy logic to find that . Example for green how to find low and high

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

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

Thanks bro . Amazing . Thank you so much

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 ?

The color ranges. I have trouble calculating for other colors like yellow, How do you calculate upper and lower bounds for all colors?

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?

can u make a video on extraction of nail using image segnmentation

Great video, worked like a charm.

Which webcam are you using???

are you a GOD? how u are guessing ranges? This is stupid. Sorry mate but this is not worthy material.

low_red = np.array([161, 155, 84]) , how you found these values (161,155,84).. How these values has been obtained?

Can you try with LAB?

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

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

veli good.

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

how the hell can i learn how to set the correct range numbers?

Brilliant!

hello sir i want to extract skin color and put it to another person ,how to do it sir?

Is this possible on a raspberry pi?

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

Very good job. Works well

Could you make to it with unity and build to android?

Is there a reason red color in background picture is not visible? because similar thing happens when i try detecting color that are at distance , idk why?

nice video, man.

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

Great video tutorial, thanks for sharing!

excuse me can you tell me what software you use to determined range of colors

You are great brother.................

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

pulls out yellow box
- a green one

I wrote the same code as yours but the 'mask' interface is always black. What is the problem? Thanks a lot

great!

thanks ✌✌

When you selected low_red and high_red in which format the colors are? RGB, BGR, HSV?

Hello! I want to create a function that for example, that if it detects a color that prints hello or something, how can i do that?

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

Check out my channel sir !
