Abstract
Summary
In this paper,we analyse main factors of threshold operator in POCS reconstruction with curvelet transform in detail and put forward a two-parameter threshold which combines three aspects. The selection condition of threshold operator parameters is different between POCS reconstruction method using curvelet transform and Fourier transform. Synthetic seismic data tests and real data example indicate the effectiveness and applicability of the threshold operator we adopt in POCS reconstruction method with curvelet transform. What’s more,the better threshold models or other factors which affect the effectiveness of POCS reconstruction method with curvelet transform need further research.
