Hi, I get error when I call the function for another function, the error like this 'Not enough input arguments'.

I have 2 function in my program

1. green_channel.m %%in bellow the code

function green = green_channel(im)

imGreen = im(:,:,2);

medGreen = medfilt2(imGreen, [3 3]);

medGreensize = imresize(medGreen,[583 947]);

green=imcomplement(medGreensize);

end

2.saturation_channel.m

function imgsat = saturation_channel(im)

imhsv=rgb2hsv(im);

imsaturation=imhsv(:,:,2);

medsat=medfilt2(imsaturation,[3 3]);

imre = imresize(medsat,[583 947]);

imgsat = uint8(imre); end

3. And the last name is hasil_kali.m

function imgkali = hasil_kali(green, imgsat)

imgkali = green.*imgsat;

end

I make that code in file hasil_kali.m to calling function from green_channel.m and saturation_channe.m, but I get error 'not enough input arguments'. Do I wrong call the function or how? please help me, I new learning, may more explain can help me. thanks

I assume hasil_kali() is the main function. And it needs to have green and imgsat already defined. How did you define green and imgsat prior to calling hasil_kali()? And how did you call hasil_kali()? You didn't just push the green run triangle, did you? Because that won't work. You need to call it from the command line or a script or another function because you must pass two input arguments (green and imgsat) to it.

Can give me the example please? I still confused

Sir, I already have a binary image after thresholding.

how I do for mask the binary with RGB image? using "cast"
