Abstract

This paper makes a comparative study on the various spatial scalable coding frameworks. The frameworks with multiple image-domain motion aligned temporal filtering at various spatial resolutions, named as multi-T+2D, are mainly investigated. First we investigate a multi-T+2D scheme based on redundant frame representation. The cross spatial layer redundancy and prediction methods are discussed. The redundancy brings significant performance loss for schemes providing wide range SNR spatial scalability. To remove the redundancy produced in the multi-resolution temporal filtering while retaining the advantage of spatial-domain motion compensation, a novel non-redundant multi-T+2D scheme is proposed. Performance comparison is given among the discussed frameworks and it shows that the proposed non-redundant multi-T+2D framework has a good performance for fully scalable video coding. We also verify that the redundant multi-T+2D framework with cross spatial layer reconstruction feedback is practical in providing narrow range SNR scalability for each spatial layer.
