Abstract：The α-trimmed vector median filtering (ATVMF) proposed in this paper is a kind of noise attenuation algorithms. Compared to vector median filter (VMF), the ATVMF can preserve the energy of the current shot as much as possible when suppressing the crosstalk from adjacent shots. Compared to the iterative inversion algorithms, this method is more efficient and robust. Tests on synthetic and field data prove the effectiveness of this method.
