Earthquake data compression method based on tensor adaptive rank truncation

摘要: The invention discloses an earthquake data compression method based on tensor adaptive rank truncation. According to the method, given conditions and a different-dimension singular value setting truncation acquired through instant higher-order decomposition, decomposition is carried out further according distribution determination magnitude; condition that rate guaranteed, peak signal noise ratio improved, effect improved; designing flow truncation, manual parameter regulation control in process can be reduced, work simplified. On basis of magnitude, anisotropy characteristics are utilized, standard deviation introduced calculate weight corresponding different dimensions, improved.
