Hi,
In your “PixelIsBlue.m” file, the syntax for declaring the function is wrong. Functions, if at all they return something, it’s a variable.
Based on your second screenshot where you are checking if a pixel is blue or not in the “if” condition from line 46 to 48.
You intended to return a variable but within the function you are just displaying true or false.
Modify your “PixelIsBlue.m” file with below approach and the rest of your code should work well with “PixelIsBlue.m” file.
function result = PixelIsBlue(r,g,b)
if r < 128 && b >= 128 && g < 128
result = true;
else
result = false;
end
If you would like to just display the whether the pixel is blue or not without returning anything, please refer to the below code:
This is just showing an alternative approach and will not work with the existing implementation with other files:
function PixelIsBlue(r,g,b)
if r < 128 && b >= 128 && g < 128
disp("true");
else
disp("false");
end
