摘要：

The L-1-norm method is one of the widely used matching filters for adaptive multiple subtraction. When the primaries and multiples are mixed together, the L-1-norm method might damage the primaries, leading to poor lateral continuity. In this paper, we propose a constrained L-1-norm method for adaptive multiple subtraction by introducing the lateral continuity constraint for the estimated primaries. We measure the lateral continuity using prediction-error filters (PEF). We illustrate our method with the synthetic Pluto dataset. The results show that the constrained L-1-norm method can simultaneously attenuate the multiples and preserve the primaries.
