Did you look up sparse in the help? Do you need further help?

From the help:
S = sparse(A) converts a full matrix to sparse form by squeezing out any zero elements
So, how many zeros are in your image? And your image is so tiny that I wonder why you're even bothering with sparse. I never use it and I deal with a lot bigger images than that.
