In standard median filtering, adjacent traces within a gather are analysed to calculate a median amplitude which is used as a reference for threshold clipping. In MDD, adjacent gathers as well as adjacent traces are analysed simultaneously, thus creating a cuboid of data which contains traces from multiple domains (see Figure 1).
The benefits of MDD over standard median filtering are two fold:
