Abstract:
1. A method for monitoring time-dependent subsurface changes between a data set and another data set, which comprises: extracting a first window of data from each data set, each first window corresponding to a region above a known or suspected area of change in the data set; extracting a second window of data from each data set, each second window corresponding to a region below the known or suspected area of change in the data set; forming a first auto-correlation of each first window and a second auto-correlation of each second window; computing a shaping filter for each data set, which transforms the first auto-correlation of each first window to the second auto-correlation of each respective second window; computing a transfer function on a computer system that transforms the shaping filter of the data set to the shaping filter of the another data set; and rendering an image of at least one of the shaping filters for each data set and the transfer function in spatially coincident alignment.
