MATLAB: Applying thresholds simultaneously in SimpleColo​rDetection​ByHue()

Question

I'm trying to use this program to detect not one but three different colors (red green blue) at the same time, applying three different thresholds. Is there a way? Try to explain each little step because I haven't used Matlab for a while and I'm a bit rusty. Thank you all!

Answer 1

Yes, basically just do each color one at a time and get a mask for each one, then OR them together.

% Set hsv thresholds for color1
maskColor1 = ........  % Create mask based on those thresholds.
% Set hsv thresholds for color2
maskColor2 = ........
% Set hsv thresholds for color3
maskColor3 = ........
% Get the mask for all 3
allThreeColorsMask = maskColor1  | maskColor2 | maskColor3;
