在 MATLAB Online 中打开

ia=imread('redline.tif');
image=im2bw(ia);
%imshow(j);
[row,column]=size(image);
grid = zeros(rows,column);
for i=1:rows
    for j=1:column
        if(image(i,j)==1)
            grid(i,j)=1;
        end
    end
end
display(grid);

Mukul - what are you trying to compare the colours to? Are you looking for those pixels that are white (==1)?

Please do not use "image" as a variable name, as that interferes with using image() as a basic MATLAB function, and confuses other people who read the code.
