The Use of Interval-Related Expert Knowledge in Processing 2-D and 3-D Data, With an Emphasis on Applications to Geosciences and Biosciences
DESCRIPTION
Processing different types of data is one of the main applications of computers, the application for which computers have been originally designed. The more data we need to process, the more computing power we need and thus, the more important it is to use (and design) faster algorithms for data processing. Even processing 1-D data often is very time-consuming, but processing 2-D data (e.g., images) and 3-D data is where we really encounter the limits of the current computer hardware abilities. Data processing algorithms sometimes produce results which contradict the expert knowledge because this knowledge was not taken into account in the algorithm. For example, a mathematical solution to a seismic inverse problem may lead to un-physically large values of density inside the Earth. At present, in such situations, researchers try to repeatedly modify (\hack") the process until the results produced by the algorithm agree with this expert knowledge.
