Classifying Complication of Seabed Terrain Based on Orthogonal Wavelet Transform

Through the wavelet analysis in the image classification and identification,the classification criterion of the seabed terrain complication is given.According to the criterion,the seabed terrain has been divided into 18 types.Through this method,the complication of seabed terrain is changed from qualitative classification to quantitative classification which provides better condition for the hydrographic technique design and the survey accuracy.The applicability of the method was validated with the practical test.
