Abstract

The present invention provides a method and a device for coding and decoding at least a part of an image comprising a plurality of samples each sample comprising at least two components and the encoded image comprising at least one filtering parameter. The filtering comprises using at least one filtering parameter as a common filtering parameter for filtering both the first component and the second component of a constructed sample.
