Abstract
The present invention relates to a method and a device for coding a multidimensional signal (LL) comprising samples to form a coded stream (FC), such as an image or a multimedia content. The method comprises: —filtering (E) original samples by applying a first filter (F, G) to obtain filtered samples (L) —coding (E) said filtered samples to obtain coded filtered samples adapted to be decoded by a decoder into decoded filtered samples, —applying (E) a lossy modification on the filtered samples to obtain modified samples (L); —determining (E, E, E) a geometric orientation of one second filter (F', G′) to be applied by the decoder to a decoded filtered sample, the determining being based on the modified samples, the original samples and a predetermined criterion, and —providing (E) said determined geometric orientations and said coded filtered samples to the decoder.
