conv2() for gray images

Hello I am trying to perform 2D convolution of 2 images.After performing the convolution i am trying to show the resultant image but no luck .Can you provide some pointers where i am making mistake ?i tried imagesc as well but it didn't show any images but only colors. i=im2double(imread('E.png')); i2=im2double(imread('BOX.png')); i=rgb2gray(i); i2=rgb2gray(i2); i3=conv2(i,i2); imshow(uint8(i3)

Your question would be easier to read if you format the code using the "{} Code" button.

I'm not sure why you are converting i3 to uint8 before passing it to imshow. Try

imshow(i3, []);

which automatically scales the grey levels.
