You can try using smoothing filters to remove the existing noise from your image.

i have to do it using wavelets. how should i proceed??

[Bjorn Gustavsson]

Why would you _have_ to use wavelets?

I've done image denoising for some time and never have _had_ to use wavelets.

Obvious answer: because it's a homework assignment.

[Harsha Vardhan Rao Avunoori]

Well if it is a homework assignment then you should go through your professor's class notes or google papers which discuss about denoising using wavelets.
