I am working on identifying the color yellow using openCV in python. I have come to this step where I have to define the lower and upper range of the color yellow in HSV.

Answer 1

take a look at this page you will find HSV values of the color you want.

For HSV, Hue range is [0,179], Saturation range is [0,255] and Value range is [0,255]. Different softwares use different scales. So if you are comparing OpenCV values with them, you need to normalize these ranges.

i guess you are searching the values like below for yellow

lower_blue = np.array([25,50,50])
upper_blue = np.array([32,255,255])
