  • data mining preprocessing techniques

    Different Data preprocessing techniques involved in data mining are data cleaning data integration data reduction and data transformation. The need for data preprocessing arises from the fact that the real-time data and many times the data of the database is often incomplete and inconsistent which may result in improper and inaccurate data mining results.

    A HORIZON PICKING The simplest approach to horizon picking is to consider horizons as sequences of local extrema of reflection intensity in the seismic image. By this way, horizon picking can be made by contour following techniques [30] based on local decisions [34], or by the use of edge detector operators (e.g., the Laplacian operator [29]-[33] or edge detectors based on nonlinear filters [61]).
