摘要:
提出了一种基于二维经验模态分解(The Bidimensional Empirical Mode Decomposition,BEMD)的水声图像声影区地貌及纹理特征提取方法.为了解决声影区的存在对水声图像特征提取的干扰问题,先对水声图像进行二维模态分解,采用Canny边缘检测器对其中的模态1或几个模态的叠加进行特征提取.实验结果表明,该方法增强了声影区内目标的特征信息,弱化了声影区的阴影边缘,是一种实用的水声图像特征提取新方法.
Abstract:
A method for extracting geomorphological and texture features of hydroacoustic images based on The Bidimensional Empirical Mode Decomposition (BEMD) is proposed. In order to solve the problem of interference from the presence of acoustic shadow area on the feature extraction of underwater acoustic images, the two-dimensional modal decomposition of the underwater acoustic images is carried out first, and the Canny edge detector is used to extract the features of mode 1 or the superposition of several modes. Experimental results show that this method enhances the feature information of targets in the acoustic shadow area and weakens the shadow edge in the acoustic shadow area, which is a practical new method for feature extraction of underwater acoustic images.
