A fine-tuned operator is used to create a series of different granularity search spaces in which most traps haven\'t been smoothed,so the influence of the traps is reduced.

The techniques mainly include uphole integral static correction,matched filtering wavelet shaping,and interactive multiple removal.

According to the problem of the difference of 3D seismic data quality affected by different acquisition factors, this paper uses generalized grid definition, bin homogenization and wavelet shaping to develop connection technique of 3D seismic process.

Saturation property of approximation of certain entire interpolation operators of exponent type in the Hlder metric;

This paper first use s the morphological operators and improved watershed algorithm to segment the image sequences in the spatial do-main,then does the inter-frame change detection using F-detection method and get the initial change detection mask(CDM)through combining temporal and spatial segmentation.
