Abstract
In the context of coding the displaced frame difference signal in an image sequence, morphological segmentation is an alternative to linear methods such as the DCT. Although these non-linear approaches offer attractive features such as edge preservation and a lack of ringing, they can introduce artefacts such as spurious edges in the reconstructed video sequence. A smoothing algorithm is described that reduces this problem and yields significant subjective quality improvements
