Convolutional sparse coding (CSC) is proposed to attenuate noise for seismic data. CSC gives a data-driven set of basis functions whose coefficients form a sparse distribution. The noise attenuation method by CSC can be divided into the training phase and the denoising phase. The seismic data with a relatively high signal-to-noise ratio are chosen for training to get the learned basis functions. Then we use all (or a subset) of the basis functions to attenuate the random or coherent noise in the seismic data. Numerical experiments on synthetic and field data indicate that the proposed method achieves good performance for denoising random and coherent noise and separating the ground roll.
