Provided are scalable video encoding and decoding methods by using a de-noise filtering. The scalable video decoding method includes generating reconstructed base layer images from a base layer image stream; determining a reference picture list including at least one of a reconstructed base layer image corresponding to a current enhancement layer image, from among the reconstructed base layer images, and a de-noise reconstructed base layer image, from an enhancement layer image stream; and reconstructing the current enhancement layer image by using a reference image that is determined from the reference picture list.
