Like I told you before, here, one of your images is not the same size as one of the others. From the error message, I can tell that image2 is not the same size as image1.

Your Image1 has been produced by im2double() so the range of Image1 is 0 to 1. But your second set of code has

Green = Image1 (i, j, 2) + 20;

so Green is going to be in the range (20+0) to (20+1), which is always going to be greater than the 0 to 1 entries already in Image1, so your "if" is always going to be true.

Note that your second block of code, involving "Green" is going to completely overwrite the output of the first block of code. Your first block might as well not be there.

Your first block could be rewritten without loops as

mask = Image1(:,:,2) > Image1(:,:,1) & Image1(:,:,2) > Image1(:,:,3);
Image2 = Image1 .* mask(:,:,[1 1 1]);

and your second block could be rewritten without loops as

mask = Image1(:,:,2) + 20 > Image1(:,:,1) & Image1(:,:,2) + 20 > Image1(:,:,3);
Image2 = Image1 .* mask(:,:,[1 1 1]);
