Attached is an example I did for another question. Adapt it.

Ur MATLAB version? creatmask function is applicable in 2022a MATLAB or not?

[Image Analyst]

I'm using 2022a but the Color Thresholder, which made createMask, has been there since r2014a. Why? Is it not working for you?

createMask does not exist as a function that accepts an rgb array, only accepts roi objects

@Walter Roberson that's a different create mask - a method of an object of class "roi". The syntax @Imran Riaz gave is exactly what you get when you use the Color Thresholder app and export the function. That is not an roi method. It is a function that does take an RGB image array.
