I have asked before about color detection using HSV Color Space,
Then I have been guided to used the LAB Color space as it is work for any color as Image Analyst answered me.
But my question not when I find the chroma value that is the square root of (a^2 + b^2)
after that how can I use this value ?? Like if I have the image attached where should I refer to and compare the calculated value 'Chroma Value' to a range of values to tell me that the object is red, or green
I need it to be done automatically
I have checked this demo, it helps but I didn't get where is the reference range I should use !
