摘要
By analyzing results of these edge extraction algorithms, the authors divide them into two types, viz. the step edge and the roof edge,and introduce the edge detection technique to data processing of gravity gradient tensor. Target boundaries are extracted directly by the step edge extraction algorithm and the roof edge extraction algorithm. The model experiments show that the target edge extracted by the edge detection algorithm is consistent with the real boundary very well. Comparing with previous boundary extraction algorithms, the new edge detection technique is more precise and continuous.
