Detection Algorithms in Multibeam Bathymetry Outliers Data

The paper introduces the current algorithms of processing outliers of multibeam bathymetry data both here and abroad.The algorithms are compared and analyzed.They include median filtering,trend surface detection,and robust estimator.The wavelet transformation steps are advanced and analyzed in feasibility.At the end of paper,the summary that synthesizing some algorithms above will improve the effect more obviously is got out.
