1. A method of processing seismic data, comprising: performing, by a system having a processor, a combined four-dimensional (4D) binning and regularization procedure on the seismic data, wherein the combined 4D binning and regularization procedure comprises: computing measures associated with regularization of the seismic data; computing measures associated with 4D binning, wherein the 4D binning includes selecting traces from the seismic data of time-lapse seismic surveys; discarding at least one trace of the seismic data that is based on considering both the regularization measures and the 4D binning measures; and processing the seismic data according to the regularization measures and 4D binning measures.
