A nonlinear partial differential equation model based on nonlocal information was proposed to remove noise and preserve the edges. 摘要针对传统扩散模型中的边界模糊问题，提出一种基于非局部信息的非线性偏微分方程去噪模型。
Before and after horizontal stack processing, to use powerful reducing noise and migration processing methods is the guarantee of obtaining high quality deep seismic profiles. 在水平叠加处理前后，分别使用强有力的去噪和归位处理技术是获取高质量深部地震剖面的保证。
