Method and apparatus for scalable video encoding using switchable de-noising filtering, and method and apparatus for scalable video decoding using switchable de-noising filtering

摘要

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 de-noise reconstructed base layer image obtained from an enhancement layer image stream and one of the reconstructed base layer images that corresponds to a current enhancement layer image; and reconstructing the current enhancement layer image based on a reference image that is included on the reference picture list.
