基于正交小波变换的海底地形复杂程度分类方法研究

Classifying Complication of Seabed Terrain Based on Orthogonal Wavelet Transform

给出了量化的海底地形复杂程度分类指标,并利用正交小波变换所具有的良好的图像识别与分类特点建立了包含18种典型海底的特征海底分类库,同时给出了海底地形复杂程度分类算法。通过分类算法将计划测量海区海底与特征海底分类库中的海底进行分类匹配,确定了计划测量海区海底的海底地形复杂程度。实例验证了该方法的有效性和适用性。

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.
