A method for decoding and reconstructing a QM associated with a picture, wherein the method comprises acquiring at least one reference QM and at least one weighting factor associated with the reference QM, wherein the reference QM is a previously decoded QM, and computing a predicted matrix using the reference QM and the weighting factor associated with the reference QM, wherein the predicted matrix is used to reconstruct the QM. In another embodiment, a method for encoding a QM associated with a picture, wherein the method comprises acquiring a first QM reference and a second QM reference, acquiring a first weighting factor that corresponds to the first QM reference and a second weighting factor that corresponds to the second QM reference, obtaining the predicted QM using the first QM reference, the second QM reference, the first weighting factor, and the second weighting factor.
