- Higher Dimensional Blue-Noise Sampling Schemes for Curvelet-Based Seismic Data Recovery
- In combination with compressive sensing, a successful reconstruction scheme called Curvelet-based Recovery by Sparsity-promoting Inversion CRSI has been developed, and has proven to be useful for seismic data processing. One of the most important issues for CRSI is the sampling scheme, which can greatly affect the quality of reconstruction. Unlike...
