<p>A method for encoding an image of pixels and for decoding a corresponding bit stream is described. More particularly, it concerns residual prediction according to a spatial scalable encoding scheme. It can be considered in the context of the Scalable (scalable video encoding SVC) extension of the HEVC standard (noted SHVC). It is proposed to simplify the computational complexity and the memory usage needed by the GRILP and DIFF inter modes by combining upsampling and motion compensation operations into a single operation and/or reducing the complexity of the linear filtering processes involved in some of the processes and/or adopt some limiting usage of these two modes when combined with bidirectional prediction. Accordingly a reduction of the complexity is achieved with, at worst, a limited loss in coding efficiency. Corresponding claims for a device and method of decoding are also disclosed.</p> |
