With the help of concept of two-direction refinement function and twodirection wavelets which are investigated refinement function of orthogonal prinples.Main result gives a complete characterization for an affine family of wavelets induced by a compactly supported to form a Riesz basis of L2.It is characterized a Riesz basis associated with an exponentially decaying mask in term of refinement function and two-direction wavelets.
