Matlab code without for loop
显示 更早的评论
Image contains 4 pixels . 0-background, 1,2 and 3 freground pixels.Can anyone help me how to improve the following code for computational efficiency? Thanks
[m n]=size(image);
for p=1:m
for q=1:n
if image(p,q)==1
image(p,q)=255;
else
image(p,q)=0;
end
end
end

I think this should work:
i = image('file.jpg')%load in whatever image it is
i(i == 1) = 255;
i(i ~= 255) = 0;
