Data thinning
Webrithm for computing the optimal thinning in polyno-mial time. Instead heuristic methods can be used, e.g., iteratively removing points from the full data set until a desired data density is reached. The most common technique for reducing the ob-servational data set is given by uniform thinning.

WebSep 25, 2024 · To greatly reduce the computational complexity in seismic data application, we propose a superpixel-based seismic data thinning approach. We further propose an integrated workflow that can be applied to practical seismic data by incorporating the DTW distance-based clustering and seismic data thinning algorithms. We evaluated the … Webto both target an area for full-resolution data density and make the satellite data more efficient by assimilating thinned data elsewhere. Typically it is too expensive for GSI to assimilate full-resolution data routinely, and data thinning is the nominal approach in GSI satellite data assimilation to solve this problem. 2.
