摘要
Artefacts arising from imperfect extrapolation of a data set subjected to filtering operation are removed by forming a model of the extrapolated data, performing a filtering process on the model and the data set to form a filtered model and a filtered data set, and adaptively subtracting the filtered model from the filtered data set. The adaptive subtraction may employ a least-square error filter.
