Image=imread('fog1.bmp');
[m n r]=size(Image)
rgb=zeros(m,n,3);
rgb(:,:,1)=Image;
rgb(:,:,2)=rgb(:,:,1);
rgb(:,:,3)=rgb(:,:,1);
Image=rgb/255;
figure,imshow(Image);
I am getting error in the line rgb(:,:,1)=Image;
Can anyone tell whats the error

Siva, you've been asking enough questions here that you should learn how to format lines as code. Here's a tip: Just simply highlight the lines of code and click the {}Code icon above the text box. That will format it so that we will see it properly. I've done it for you this time but try to do it yourself next time - it's not hard. Thanks!

Image=imread('fog1.bmp');
if size(Image,3)==3
Image=rgb2gray(Image);
end
[m n r]=size(Image);
rgb=zeros(m,n,3);
rgb(:,:,1)=Image;
rgb(:,:,2)=rgb(:,:,1);
rgb(:,:,3)=rgb(:,:,1);
Image=rgb/255;
figure,imshow(Image);
Try this code...

Hi,
what's the value of r? One? Or three? I guess your Image is already an RGB image, only that R, G and B are always equal (and therefore you have gray) ...

So the proper code would most likely be:
rgbImage = imread('fog1.bmp');
[rows columns numberOfColorChannels] = size(rgbImage);
if numberOfColorChannels == 1
% It's monochrome, so convert to color.
rgbImage = cat(3, rgbImage, rgbImage, rgbImage);
end
imshow(rgbImage);
