i have decomposed my image using svd… and modified the singular values..now i have three vectors..U S and V..can u pls help me to reconstruct my image.is there any keywords that would perform the inverse work of svd??

What do you mean by "the inverse of SVD"? The SVD is a decomposition: A = U*S*V' so reconstructing A just requires performing the multiplication.
