The invention relates to a method for coding a sequence of digitalised images (I) that consist of a plurality of pixels. For each of the images, a signal (S) is coded that is dependent on the image content of the images in question, the uncoded signal being reconstructed and reconstructed images being derived therefrom in the course of the coding process. Said reconstructed images (RI) undergo filtering (LF) wherein a particular reconstructed image (RI) is divided into partitions (PA1, PA2) with one or more filter parameters (FP) being defined for each partition (PA1, PA2). According to the invention, at least some of the partitions (PI1, PI2) are respectively described using one or more parameters of a function (F1, F2, F3) that describes the curve of pixels within a predetermined image region (B), said pixel curve dividing the predetermined image region into at least two partitions (PA1, PA2). |
